6d68b2ab78 describe: teach --match to handle branches and remotes
When `git describe` uses `--match`, it matches only tags, basically
ignoring the `--all` argument even when it is specified.

Fix it by also matching branch name and $remote_name/$remote_branch_name,
for remote-tracking references, with the specified patterns. Update
documentation accordingly and add tests.

b0176ce6b5 builtin/describe: introduce --broken flag
git-describe tells you the version number you're at, or errors out, e.g.
when you run it outside of a repository, which may happen when downloading
a tar ball instead of using git to obtain the source code.

To keep this property of only erroring out, when not in a repository,
severe (submodule) errors must be downgraded to reporting them gently
instead of having git-describe error out completely.

To achieve that a flag '--broken' is introduced, which is in the same
vein as '--dirty' but uses an actual child process to check for dirtiness.
When that child dies unexpectedly, we'll append '-broken' instead of
'-dirty'.

77d21f29ea describe: teach describe negative pattern matches
Teach git-describe the `--exclude` option which will allow specifying
a glob pattern of tags to ignore. This can be combined with the
`--match` patterns to enable more flexibility in determining which tags
to consider.

For example, suppose you wish to find the first official release tag
that contains a certain commit. If we assume that official release tags
are of the form "v*" and pre-release candidates include "*rc*" in their
name, we can now find the first release tag that introduces the commit
abcdef:

  git describe --contains --match="v*" --exclude="*rc*" abcdef

Add documentation, tests, and completion for this change.

43f8080eaf describe: teach --match to accept multiple patterns
Teach `--match` to be accepted multiple times, accumulating a list of
patterns to match into a string list. Each pattern is inclusive, such
that a tag need only match one of the provided patterns to be
considered for matching.

This extension is useful as it enables more flexibility in what tags
match, and may avoid the need to run the describe command multiple
times to get the same result.

Add tests and update the documentation for this change.

This was obtained with:

e95c3fb54f Merge branch 'sg/describe-contains'
"git describe" without argument defaulted to describe the HEAD
commit, but "git describe --contains" didn't.  Arguably, in a
repository used for active development, such defaulting would not
be very useful as the tip of branch is typically not tagged, but it
is better to be consistent.

* sg/describe-contains:
  describe --contains: default to HEAD when no commit-ish is given

2bd07065c3 describe --contains: default to HEAD when no commit-ish is given
'git describe --contains' doesn't default to HEAD when no commit is
given, and it doesn't produce any output, not even an error:

  ~/src/git ((v2.5.0))$ ./git describe --contains
  ~/src/git ((v2.5.0))$ ./git describe --contains HEAD
  v2.5.0^0

Unlike other 'git describe' options, the '--contains' code path is
implemented by calling 'name-rev' with a bunch of options plus all the
commit-ishes that were passed to 'git describe'.  If no commit-ish was
present, then 'name-rev' got invoked with none, which then leads to the
behavior illustrated above.

Porcelain commands usually default to HEAD when no commit-ish is given,
and 'git describe' already does so in all other cases, so it should do
so with '--contains' as well.

Pass HEAD to 'name-rev' when no commit-ish is given on the command line
to make '--contains' behave consistently with other 'git describe'
options.  While at it, use argv_array_pushv() instead of the loop to
pass commit-ishes to 'git name-rev'.

'git describe's short help already indicates that the commit-ish is
optional, but the synopsis in the man page doesn't, so update it
accordingly as well.

831e61f80f Documentation: do not mention .git/refs/* directories
It is an implementation detail that a new tag is created by adding a
file in the .git/refs/tags directory.  The only thing the user needs
to know is that a "git tag" creates a ref in the refs/tags namespace,
and without "-f", it does not overwrite an existing tag.

Inspired by a report from 乙酸鋰 <ch3cooli@gmail.com>; I think I
caught all the existing mention in Documentation/ directory in the

48bb914ed6 doc: drop author/documentation sections from most pages
The point of these sections is generally to:

  1. Give credit where it is due.

  2. Give the reader an idea of where to ask questions or
     file bug reports.

But they don't do a good job of either case. For (1), they
are out of date and incomplete. A much more accurate answer
can be gotten through shortlog or blame.  For (2), the
correct contact point is generally git@vger, and even if you
wanted to cc the contact point, the out-of-date and
incomplete fields mean you're likely sending to somebody
useless.

So let's drop the fields entirely from all manpages except
git(1) itself. We already point people to the mailing list
for bug reports there, and we can update the Authors section
to give credit to the major contributors and point to
shortlog and blame for more information.

Each page has a "This is part of git" footer, so people can
follow that to the main git manpage.

29b9a66f28 Change incorrect uses of "remote branch" meaning "remote-tracking"
"remote branch" is a branch hosted in a remote repository, while
"remote-tracking branch" is a copy of such branch, hosted locally.
The distinction is subtle when the copy is up-to-date, but rather
fundamental to understand what "git fetch" and "git push" do.

This patch should fix all incorrect usages in Documentation/ directory.

0b444cdb19 Documentation: spell 'git cmd' without dash throughout
The documentation was quite inconsistent when spelling 'git cmd' if it
only refers to the program, not to some specific invocation syntax:
both 'git-cmd' and 'git cmd' spellings exist.

The current trend goes towards dashless forms, and there is precedent
in 647ac70 (git-svn.txt: stop using dash-form of commands.,
2009-07-07) to actively eliminate the dashed variants.

Replace 'git-cmd' with 'git cmd' throughout, except where git-shell,
git-cvsserver, git-upload-pack, git-receive-pack, and
git-upload-archive are concerned, because those really live in the
$PATH.

9f67d2e827 Teach "git describe" --dirty option
With the --dirty option, git describe works on HEAD but append s"-dirty"
iff the contents of the work tree differs from HEAD.  E.g.

  $ git describe --dirty
  v1.6.5-15-gc274db7
  $ echo >> Makefile
  $ git describe --dirty
  v1.6.5-15-gc274db7-dirty

The --dirty option can also be used to specify what is appended, instead
of the default string "-dirty".

  $ git describe --dirty=.mod
  v1.6.5-15-gc274db7.mod

Many build scripts use `git describe` to produce a version number based on
the description of HEAD (on which the work tree is based) + saying that if
the build contains uncommitted changes.  This patch helps the writing of
such scripts since `git describe --dirty` does directly the intended thing.

Three possiblities were considered while discussing this new feature:

1. Describe the work tree by default and describe HEAD only if "HEAD" is
   explicitly specified

     Pro: does the right thing by default (both for users and for scripts)
     Pro: other git commands that works on the work tree by default
     Con: breaks existing scripts used by the Linux kernel and other projects

2. Use --worktree instead of --dirty

     Pro: does what it says: "git describe --worktree" describes the work tree
     Con: other commands do not require a --worktree option when working
          on the work tree (it often is the default mode for them)
     Con: unusable with an optional value: "git describe --worktree=.mod"
	  is quite unintuitive.

3. Use --dirty as in this patch

     Pro: makes sense to specify an optional value (what the dirty mark is)
     Pro: does not have any of the big cons of previous alternatives
	  * does not break scripts
	  * is not inconsistent with other git commands

This patch takes the third approach.

b1889c36d8 Documentation: be consistent about "git-" versus "git "
Since the git-* commands are not installed in $(bindir), using
"git-command <parameters>" in examples in the documentation is
not a good idea. On the other hand, it is nice to be able to
refer to each command using one hyphenated word. (There is no
escaping it, anyway: man page names cannot have spaces in them.)

This patch retains the dash in naming an operation, command,
program, process, or action. Complete command lines that can
be entered at a shell (i.e., without options omitted) are
made to use the dashless form.

The changes consist only of replacing some spaces with hyphens
and vice versa. After a "s/ /-/g", the unpatched and patched
versions are identical.

2c33f75754 Teach git-describe --exact-match to avoid expensive tag searches
Sometimes scripts want (or need) the annotated tag name that exactly
matches a specific commit, or no tag at all.  In such cases it can be
difficult to determine if the output of `git describe $commit` is a
real tag name or a tag+abbreviated commit.  A common idiom is to run
git-describe twice:

  if test $(git describe $commit) = $(git describe --abbrev=0 $commit)
  ...

but this is a huge waste of time if the caller is just going to pick a
different method to describe $commit or abort because it is not exactly
an annotated tag.

Setting the maximum number of candidates to 0 allows the caller to ask
for only a tag that directly points at the supplied commit, or to have
git-describe abort if no such item exists.

Junio suggested we make `git describe --contains` run the correct
tool, `git name-rev`, and that's exactly what we do here.  The output
of name-rev was adjusted slightly through the new --name-only option,
allowing describe to execv into name-rev and maintain its current
output format.

8713ab3079 Improve git-describe performance by reducing revision listing.
My prior version of git-describe ran very slowly on even reasonably
sized projects like git.git and linux.git as it tended to identify
a large number of possible tags and then needed to generate the
revision list for each of those tags to sort them and select the
best tag to describe the input commit.

All we really need is the number of commits in the input revision
which are not in the tag.  We can generate these counts during
the revision walking and tag matching loop by assigning a color to
each tag and coloring the commits as we walk them.  This limits us
to identifying no more than 26 possible tags, as there is limited
space available within the flags field of struct commit.

The limitation of 26 possible tags is hopefully not going to be a
problem in real usage, as most projects won't create 26 maintenance
releases and merge them back into a development trunk after the
development trunk was tagged with a release candidate tag.  If that
does occur git-describe will start to revert to its old behavior of
using the newer maintenance release tag to describe the development
trunk, rather than the development trunk's own tag.  The suggested
workaround would be to retag the development trunk's tip.

However since even 26 possible tags can take a while to generate a
description for on some projects I'm defaulting the limit to 10 but
offering the user --candidates to increase the number of possible
matches if they need a more accurate result.  I specifically chose
10 for the default as it seems unlikely projects will have more
than 10 maintenance releases merged into a development trunk before
retagging the development trunk, and it seems to perform about the
same on linux.git as v1.4.4.4 git-describe.

A large amount of debugging information was also added during
the development of this change, so I've left it in to be toggled
on with --debug.  It may be useful to the end user to help them
understand why git-describe took one particular tag over another.

3742506578 Some doc typo fixes
All should be clear enough, except perhaps committish / commitish.
I just kept the more-used one within the current docs.

[jc: with rephrasing of check-ref-format description later discussed
 on the list]
