7a14acdbe6 doc: point to diff attribute in patch format docs
From the documentation for generating patch text with diff-related
commands, refer to the documentation for the diff attribute.

This attribute influences the way that patches are generated, but this
was previously not mentioned in e.g., the git-diff manpage.

Mention --diff-merges instead of -m in a note to merge formats to aid

anyway.

17bae89476 git.txt: correct stale 'GIT_EXTERNAL_DIFF' description
In fde97d8ac6 (Update documentation to remove incorrect GIT_DIFF_OPTS
example., 2006-11-27), the description of the 'GIT_EXTERNAL_DIFF'
variable was moved from 'diff-format.txt' to 'git.txt', and the
documentation was updated to remove a 'diff(1)' invocation since Git did
not use an external diff program anymore by default.

However, the description of 'GIT_EXTERNAL_DIFF' still mentions "instead
of the diff invocation described above", which is confusing.

Correct that outdated sentence.

Also, link to git(1) in 'diff-generate-patch.txt' when GIT_DIFF_OPTS and
GIT_EXTERNAL_DIFF are mentioned, so that users can easily know what
these variables are about.

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.

d76ce4f734 log,diff-tree: add --combined-all-paths option
The combined diff format for merges will only list one filename, even if
rename or copy detection is active.  For example, with raw format one
might see:

  ::100644 100644 100644 fabadb8 cc95eb0 4866510 MM	describe.c
  ::100755 100755 100755 52b7a2d 6d1ac04 d2ac7d7 RM	bar.sh
  ::100644 100644 100644 e07d6c5 9042e82 ee91881 RR	phooey.c

This doesn't let us know what the original name of bar.sh was in the
first parent, and doesn't let us know what either of the original names
of phooey.c were in either of the parents.  In contrast, for non-merge
commits, raw format does provide original filenames (and a rename score
to boot).  In order to also provide original filenames for merge
commits, add a --combined-all-paths option (which must be used with
either -c or --cc, and is likely only useful with rename or copy
detection active) so that we can print tab-separated filenames when
renames are involved.  This transforms the above output to:

  ::100644 100644 100644 fabadb8 cc95eb0 4866510 MM	desc.c	desc.c	desc.c
  ::100755 100755 100755 52b7a2d 6d1ac04 d2ac7d7 RM	foo.sh	bar.sh	bar.sh
  ::100644 100644 100644 e07d6c5 9042e82 ee91881 RR	fooey.c	fuey.c	phooey.c

Further, in patch format, this changes the from/to headers so that
instead of just having one "from" header, we get one for each parent.
For example, instead of having

  --- a/phooey.c
  +++ b/phooey.c

we would see

  --- a/fooey.c
  --- a/fuey.c
  +++ b/phooey.c

Similarly to the previous commit, use backquotes instead of
forward-quotes, for long options.

This was obtained with:

  perl -pi -e "s/'(--[a-z][a-z=<>-]*)'/\`\$1\`/g" *.txt

and manual tweak to remove false positive in ascii-art (o'--o'--o' to
describe rewritten history).

23f8239bbe doc: typeset short command-line options as literal
It was common in our documentation to surround short option names with
forward quotes, which renders as italic in HTML. Instead, use backquotes
which renders as monospace. This is one more step toward conformance to
Documentation/CodingGuidelines.

47d81b5c7a doc: more consistency in environment variables format
Wrap with backticks (monospaced font) unwrapped or single-quotes wrapped
(italic type) environment variables which are followed by the word
"environment". It was obtained with:

perl -pi -e "s/\'?(\\\$?[0-9A-Z\_]+)\'?(?= environment ?)/\`\1\`/g" *.txt

One of the main purposes is to stick to the CodingGuidelines as possible so
that people writting new documentation by mimicking the existing are more likely
to have it right (even if they didn't read the CodingGuidelines).

e08bc7a9ec doc: fix misrendering due to `single quote'
AsciiDoc misparses some text that contains a `literal`
word followed by a fancy `single quote' word, and treats
everything from the start of the literal to the end of the
quote as a single-quoted phrase.

We can work around this by switching the latter to be a
literal, as well. In the first case, this is perhaps what
was intended anyway, as it makes us consistent with the the
earlier literals in the same paragraph. In the second, the
output is arguably better, as we will format our commit
references as <code> blocks.

6cf378f0cb docs: stop using asciidoc no-inline-literal
In asciidoc 7, backticks like `foo` produced a typographic
effect, but did not otherwise affect the syntax. In asciidoc
8, backticks introduce an "inline literal" inside which markup
is not interpreted. To keep compatibility with existing
documents, asciidoc 8 has a "no-inline-literal" attribute to
keep the old behavior. We enabled this so that the
documentation could be built on either version.

It has been several years now, and asciidoc 7 is no longer
in wide use. We can now decide whether or not we want
inline literals on their own merits, which are:

  1. The source is much easier to read when the literal
     contains punctuation. You can use `master~1` instead
     of `master{tilde}1`.

  2. They are less error-prone. Because of point (1), we
     tend to make mistakes and forget the extra layer of
     quoting.

This patch removes the no-inline-literal attribute from the
Makefile and converts every use of backticks in the
documentation to an inline literal (they must be cleaned up,
or the example above would literally show "{tilde}" in the
output).

Problematic sites were found by grepping for '`.*[{\\]' and
examined and fixed manually. The results were then verified
by comparing the output of "html2text" on the set of
generated html pages. Doing so revealed that in addition to
making the source more readable, this patch fixes several
formatting bugs:

  - HTML rendering used the ellipsis character instead of
    literal "..." in code examples (like "git log A...B")

  - some code examples used the right-arrow character
    instead of '->' because they failed to quote

  - api-config.txt did not quote tilde, and the resulting
    HTML contained a bogus snippet like:

      <tt><sub></tt> foo <tt></sub>bar</tt>

    which caused some parsers to choke and omit whole
    sections of the page.

  - git-commit.txt confused ``foo`` (backticks inside a
    literal) with ``foo'' (matched double-quotes)

  - mentions of `A U Thor <author@example.com>` used to
    erroneously auto-generate a mailto footnote for
    author@example.com

  - the description of --word-diff=plain incorrectly showed
    the output as "[-removed-] and {added}", not "{+added+}".

  - using "prime" notation like:

      commit `C` and its replacement `C'`

    confused asciidoc into thinking that everything between
    the first backtick and the final apostrophe were meant
    to be inside matched quotes

  - asciidoc got confused by the escaping of some of our
    asterisks. In particular,

      `credential.\*` and `credential.<url>.\*`

    properly escaped the asterisk in the first case, but
    literally passed through the backslash in the second
    case.

e0adb84cc6 diff format documentation: clarify --cc and -c
The description was unclear if -c or --cc was the default (--cc is for
some commands), and incorrectly implied that the default applies to
all the diff generating commands.

Most importantly, "log" does not default to "--cc" (it defaults to
"--no-merges") and "log -p" obeys the user's wish to see non-combined
format.  Only "diff" (during merge and three-blob comparison) and
"show" use --cc as the default.

88d9d45d07 git log -p -m: document -m and honor --first-parent
git log -p -m is used to show one merge entry per parent, with an
appropriate diff; this can be useful when examining histories where
full set of changes introduced by a merged branch is interesting, not
only the conflicts.

This patch properly documents the -m switch, which has so far been
mentioned only as a fairly special diff-tree flag.

It also makes the code show full patch entry only for the first parent
when --first-parent is used. Thus:

	git log -p -m --first-parent

will show the history from the "main branch perspective", while also
including full diff of changes introduced by other merged in branches.
