11a3d3aadd git-rev-list.txt: prune options in synopsis
The synopsis section in git-rev-list.txt has grown to be a huge list
that probably needs its own synopsis. Since the list is huge, users may
be given the false impression that the list is complete, however it is
not. It is missing many of the available options.

Since the list of options in the synopsis is not only annoying but
actively harmful, replace it with `[<options>]` so users know to
explicitly look through the documentation for further information.

While we're at it, update the optional path notation so that it is more
modern.

c4d2f6143a user-manual.txt: render ASCII art correctly under Asciidoctor
This commit is similar to 379805051d ("Documentation: render revisions
correctly under Asciidoctor", 2018-05-06) and is a no-op with AsciiDoc.

When creating a literal block from an indented block without any sort of
delimiters, Asciidoctor strips off all leading whitespace, resulting in
a misrendered ASCII drawing. Use an explicit literal block to indicate
to Asciidoctor that we want to keep the leading whitespace. Drop the
common indentation for all lines to make this a no-op with AsciiDoc.

dba3734103 asciidoctor-extensions.rb: handle "book" doctype in linkgit
user-manual.txt is the only file we process using the "book" doctype.
When we use AsciiDoc, user-manual.conf ensures that the linkgit macro
expands into something like

  <ulink url="git-foo.html">git-foo(1)</ulink>

in user-manual.xml, which we then process into a clickable link, both in
user-manual.html and user-manual.pdf. With Asciidoctor,
user-manual.conf is ignored (this is expected) and our
Asciidoctor-specific implementation of linkgit kicks in:

  <citerefentry>
    <refentrytitle>git-foo</refentrytitle><manvolnum>1</manvolnum>
  </citerefentry>

This eventually renders as "git-foo(1)", which is not bad, but it
doesn't turn into a link.

Teach our Asciidoctor-specific implementation of the linkgit macro that
if the doctype is "book", we should emit <ulink .../> just like we do
with AsciiDoc. While we're doing this, future-proof by supporting a
"prefix". The implementation in user-manual.conf doesn't support this,
and we don't need this for now because user-manual.txt is the only file
we process this way (and it's immediately in Documentation/).

fd5b820d9c user-manual.txt: change header notation
When AsciiDoc processes user-manual.txt, it generates a book containing
chapters containing sections. So for example, we have chapter 6,
"Advanced branch management", which contains four relatively short
sections, 6.1-6.4. Asciidoctor generates a book containing *parts*
containing *chapters* instead. So part 6, "Advanced branch management"
contains four short chapters, 1-4. This looks a bit odd.

To make AsciiDoc (8.6.10) and Asciidoctor (1.5.5) handle these the same,
change from indicating chapters like so:

  [[foobar]]
  Foobar
  ======

to doing it like so:

  [[foobar]]
  == Foobar

Same thing for sections (line of dashes to ===), subsections (line of
tildes to ====) and subsubsections (line of carets to =====). Mark the
appendices with "[appendix]", which both AsciiDoc and Asciidoctor
understand. This means we need to drop the "Appendix X: " from their
titles, or those "Appendix X: " would be included literally in the name
of the appendix.

This commit is a no-op for AsciiDoc: The generated user-manual.xml is
identical before and after this patch. Asciidoctor now creates the same
chapter-section-subsection structure as AsciiDoc.

Changing the book title at the start of the document to similarly use
"=" instead of a line of equal signs makes no difference with any of the
engines, but let's do that change anyway for consistency.

09487f2cba clean: avoid removing untracked files in a nested git repository
Users expect files in a nested git repository to be left alone unless
sufficiently forced (with two -f's).  Unfortunately, in certain
circumstances, git would delete both tracked (and possibly dirty) files
and untracked files within a nested repository.  To explain how this
happens, let's contrast a couple cases.  First, take the following
example setup (which assumes we are already within a git repo):

   git init nested
   cd nested
   >tracked
   git add tracked
   git commit -m init
   >untracked
   cd ..

In this setup, everything works as expected; running 'git clean -fd'
will result in fill_directory() returning the following paths:
   nested/
   nested/tracked
   nested/untracked
and then correct_untracked_entries() would notice this can be compressed
to
   nested/
and then since "nested/" is a directory, we would call
remove_dirs("nested/", ...), which would
check is_nonbare_repository_dir() and then decide to skip it.

However, if someone also creates an ignored file:
   >nested/ignored
then running 'git clean -fd' would result in fill_directory() returning
the same paths:
   nested/
   nested/tracked
   nested/untracked
but correct_untracked_entries() will notice that we had ignored entries
under nested/ and thus simplify this list to
   nested/tracked
   nested/untracked
Since these are not directories, we do not call remove_dirs() which was
the only place that had the is_nonbare_repository_dir() safety check --
resulting in us deleting both the untracked file and the tracked (and
possibly dirty) file.

One possible fix for this issue would be walking the parent directories
of each path and checking if they represent nonbare repositories, but
that would be wasteful.  Even if we added caching of some sort, it's
still a waste because we should have been able to check that "nested/"
represented a nonbare repository before even descending into it in the
first place.  Add a DIR_SKIP_NESTED_GIT flag to dir_struct.flags and use
it to prevent fill_directory() and friends from descending into nested
git repos.

With this change, we also modify two regression tests added in commit
91479b9c72 ("t7300: add tests to document behavior of clean and nested
git", 2015-06-15).  That commit, nor its series, nor the six previous
iterations of that series on the mailing list discussed why those tests
coded the expectation they did.  In fact, it appears their purpose was
simply to test _existing_ behavior to make sure that the performance
changes didn't change the behavior.  However, these two tests directly
contradicted the manpage's claims that two -f's were required to delete
files/directories under a nested git repository.  While one could argue
that the user gave an explicit path which matched files/directories that
were within a nested repository, there's a slippery slope that becomes
very difficult for users to understand once you go down that route (e.g.
what if they specified "git clean -f -d '*.c'"?)  It would also be hard
to explain what the exact behavior was; avoid such problems by making it
really simple.

Also, clean up some grammar errors describing this functionality in the
git-clean manpage.

Finally, there are still a couple bugs with -ffd not cleaning out enough
(e.g.  missing the nested .git) and with -ffdX possibly cleaning out the
wrong files (paying attention to outer .gitignore instead of inner).
This patch does not address these cases at all (and does not change the
behavior relative to those flags), it only fixes the handling when given
a single -f.  See
https://public-inbox.org/git/20190905212043.GC32087@szeder.dev/ for more
discussion of the -ffd[X?] bugs.

e86bbcf987 clean: disambiguate the definition of -d
The -d flag pre-dated git-clean's ability to have paths specified.  As
such, the default for git-clean was to only remove untracked files in
the current directory, and -d existed to allow it to recurse into
subdirectories.

The interaction of paths and the -d option appears to not have been
carefully considered, as evidenced by numerous bugs and a dearth of
tests covering such pairings in the testsuite.  The definition turns out
to be important, so let's look at some of the various ways one could
interpret the -d option:

  A) Without -d, only look in subdirectories which contain tracked
     files under them; with -d, also look in subdirectories which
     are untracked for files to clean.

  B) Without specified paths from the user for us to delete, we need to
     have some kind of default, so...without -d, only look in
     subdirectories which contain tracked files under them; with -d,
     also look in subdirectories which are untracked for files to clean.

The important distinction here is that choice B says that the presence
or absence of '-d' is irrelevant if paths are specified.  The logic
behind option B is that if a user explicitly asked us to clean a
specified pathspec, then we should clean anything that matches that
pathspec.  Some examples may clarify.  Should

   git clean -f untracked_dir/file

remove untracked_dir/file or not?  It seems crazy not to, but a strict
reading of option A says it shouldn't be removed.  How about

   git clean -f untracked_dir/file1 tracked_dir/file2

or

   git clean -f untracked_dir_1/file1 untracked_dir_2/file2

?  Should it remove either or both of these files?  Should it require
multiple runs to remove both the files listed?  (If this sounds like a
crazy question to even ask, see the commit message of "t7300: Add some
testcases showing failure to clean specified pathspecs" added earlier in
this patch series.)  What if -ffd were used instead of -f -- should that
allow these to be removed?  Should it take multiple invocations with
-ffd?  What if a glob (such as '*tracked*') were used instead of
spelling out the directory names?  What if the filenames involved globs,
such as

   git clean -f '*.o'

or

   git clean -f '*/*.o'

?

The current documentation actually suggests a definition that is
slightly different than choice A, and the implementation prior to this
series provided something radically different than either choices A or
B. (The implementation, though, was clearly just buggy).  There may be
other choices as well.  However, for almost any given choice of
definition for -d that I can think of, some of the examples above will
appear buggy to the user.  The only case that doesn't have negative
surprises is choice B: treat a user-specified path as a request to clean
all untracked files which match that path specification, including
recursing into any untracked directories.

Change the documentation and basic implementation to use this
definition.

There were two regression tests that indirectly depended on the current
implementation, but neither was about subdirectory handling.  These two
tests were introduced in commit 5b7570cfb4 ("git-clean: add tests for
relative path", 2008-03-07) which was solely created to add coverage for
the changes in commit fb328947c8e ("git-clean: correct printing relative
path", 2008-03-07).  Both tests specified a directory that happened to
have an untracked subdirectory, but both were only checking that the
resulting printout of a file that was removed was shown with a relative
path.  Update these tests appropriately.

6fae6bd518 diff, log doc: say "patch text" instead of "patches"
diff, log doc: say "patch text" instead of "patches"

A poster on Stackoverflow was confused that the documentation of git-log
promised to generate "patches" or "patch files" with -p, but there were
none to be found. Rewrite the corresponding paragraph to talk about
"patch text" to avoid the confusion.

Shorten the language to say "X does Y" in place of "X does not Z, but Y".

Cross-reference the referred-to commands like the rest of the file does.

Enumerate git-show because it includes the description as well.

Mention porcelain commands before plumbing commands because I guess that
the paragraph is read more frequently in their context.

83b0b8953e doc-diff: replace --cut-header-footer with --cut-footer
After the previous commit, AsciiDoc and Asciidoctor render the manpage
headers identically, so we no longer need the "cut the header" part of
our `--cut-header-footer` option. We do still need the "cut the footer"
part, though. The previous commits improved the rendering of the footer
in Asciidoctor by quite a bit, but the two programs still disagree on
how to format the date in the footer: 01/01/1970 vs 1970-01-01.

We could keep using `--cut-header-footer`, but it would be nice if we
had a slightly smaller hammer `--cut-footer` that would be less likely
to hide regressions. Rather than simply adding such an option, let's
also drop `--cut-header-footer`, i.e., rework it to lose the "header"
part of its name and functionality.

`--cut-header-footer` is just a developer tool and it probably has no
more than a handful of users, so we can afford to be aggressive.

7a30134358 asciidoctor-extensions: provide <refmiscinfo/>
As can be seen from the previous commit, there are three attributes that
we provide to AsciiDoc through asciidoc.conf. Asciidoctor ignores that
file. After that patch, newer versions of Asciidoctor pick up the
`manmanual` and `mansource` attributes as we invoke `asciidoctor`, but
they don't pick up `manversion`. ([1] says: "Not used by Asciidoctor.")
Older versions (<1.5.7) don't handle these attributes at all. As a
result, we are missing one or three `<refmiscinfo/>` tags in each
xml-file produced when we build with Asciidoctor.

Because of this, xmlto doesn't include the Git version number in the
rendered manpages. And in particular, with versions <1.5.7, the manpage
footers instead contain the fairly ugly "[FIXME: source]".

That Asciidoctor ignores asciidoc.conf is nothing new. This is why we
implement the `linkgit:` macro in asciidoc.conf *and* in
asciidoctor-extensions.rb. Follow suit and provide these tags in
asciidoctor-extensions.rb, using a "postprocessor" extension where we
just search and replace in the XML, treated as text.

We may consider a few alternatives:

  * Inject these lines into the xml-files from the *Makefile*, e.g.,
    using `sed`. That would reduce repetition, but it feels wrong to
    impose another step and another risk on the AsciiDoc-processing only
    to benefit the Asciidoctor-one.

  * I tried providing a "docinfo processor" to inject these tags, but
    could not figure out how to "merge" the two <refmeta/> sections that
    resulted. To avoid xmlto barfing on the result, I needed to use
    `xmlto --skip-validation ...`, which seems unfortunate.

Let's instead inject the missing tags using a postprocessor. We'll make
it fairly obvious that we aim to inject the exact same three lines of
`<refmiscinfo/>` that asciidoc.conf provides. We inject them in
*post*-processing so we need to do the variable expansion ourselves. We
do introduce the bug that asciidoc.conf already has in that we won't do
any escaping, e.g., of funky versions like "some v <2.25, >2.20".

The postprocessor we add here works on the XML as raw text and doesn't
really use the full potential of XML to do a more structured injection.
This is actually precisely what the Asciidoctor User Manual does in its
postprocessor example [2]. I looked into two other approaches:

  1. The nokogiri library is apparently the "modern" way of doing XML
     in ruby. I got it working fairly easily:
        require 'nokogiri'
        doc = Nokogiri::XML(output)
        doc.search("refmeta").each { |n| n.add_child(new_tags) }
        output = doc.to_xml
     However, this adds another dependency (e.g., the "ruby-nokogiri"
     package on Ubuntu). Using Asciidoctor is not our default, but it
     will probably need to become so soon. Let's avoid adding a
     dependency just so that we can say "search...add_child" rather than
     "sub(regex...)".

  2. The older REXML is apparently always(?) bundled with ruby, but I
     couldn't even parse the original document:
        require 'rexml/document'
        doc = REXML::Document.new(output)
        ...
     The error was "no implicit conversion of nil into String" and I
     stopped there.

I don't think it's unlikely that doing a plain old search-and-replace
will work just as fine or better compared to parsing XML and worrying
about libraries and library versions.

226daba280 Doc/Makefile: give mansource/-version/-manual attributes
Rather than hardcoding "Git Manual" and "Git" as the manual and source
in asciidoc.conf, provide them as attributes `manmanual` and
`mansource`. Rename the `git_version` attribute to `manversion`.

These new attribute names are not arbitrary, see, e.g., [1].

For AsciiDoc (8.6.10) and Asciidoctor <1.5.7, this is a no-op. Starting
with Asciidoctor 1.5.7, `manmanual` and `mansource` actually end up in
the xml-files and eventually in the rendered manpages. In particular,
the manpage headers now render just as with AsciiDoc.

No versions of Asciidoctor pick up the `manversion` [2], and older
versions don't pick up any of these attributes. -- We'll fix that with a
bit of a hack in the next commit.

40e747e89d git-submodule.txt: fix AsciiDoc formatting error
In b57e8119e6 (submodule: teach set-branch subcommand, 2019-02-08), the
`set-branch` subcommand was added for submodules. When the documentation
was written, the syntax for a "index term" in AsciiDoc was
accidentally used. This caused the documentation to be rendered as

	set-branch -d|--default)|(-b|--branch <branch> [--] <path>

instead of

	set-branch ((-d|--default)|(-b|--branch <branch>)) [--] <path>

In addition to this, the original documentation was possibly confusing
as it made it seem as if the `-b` option didn't accept a `<branch>`
argument.

Break `--default` and `--branch` into their own separate invocations to
make it obvious that these options are mutually exclusive. Also, this
removes the surrounding parentheses so that the "index term" syntax is
not triggered.
