Thomas Rast 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.

git-name-rev(1)
===============
NAME
----
git-name-rev - Find symbolic names for given revs
SYNOPSIS
--------
[verse]
'git name-rev' [--tags] [--refs=<pattern>]
( --all | --stdin | <committish>... )
DESCRIPTION
-----------
Finds symbolic names suitable for human digestion for revisions given in any
format parsable by 'git rev-parse'.
OPTIONS
-------
--tags::
Do not use branch names, but only tags to name the commits
--refs=<pattern>::
Only use refs whose names match a given shell pattern.
--all::
List all commits reachable from all refs
--stdin::
Read from stdin, append "(<rev_name>)" to all sha1's of nameable
commits, and pass to stdout
--name-only::
Instead of printing both the SHA-1 and the name, print only
the name. If given with --tags the usual tag prefix of
"tags/" is also omitted from the name, matching the output
of `git-describe` more closely.
--no-undefined::
Die with error code != 0 when a reference is undefined,
instead of printing `undefined`.
--always::
Show uniquely abbreviated commit object as fallback.
EXAMPLE
-------
Given a commit, find out where it is relative to the local refs. Say somebody
wrote you about that fantastic commit 33db5f4d9027a10e477ccf054b2c1ab94f74c85a.
Of course, you look into the commit, but that only tells you what happened, but
not the context.
Enter 'git name-rev':
------------
% git name-rev 33db5f4d9027a10e477ccf054b2c1ab94f74c85a
33db5f4d9027a10e477ccf054b2c1ab94f74c85a tags/v0.99~940
------------
Now you are wiser, because you know that it happened 940 revisions before v0.99.
Another nice thing you can do is:
------------
% git log | git name-rev --stdin
