Retire git-runstatus for real.

The command was removed from the builtin command list and there was no
way to invoke it, but the code was still there.

-git-runstatus(1)
-================
-
-NAME
-----
-git-runstatus - A helper for git-status and git-commit
-
-
-SYNOPSIS
---------
-'git-runstatus' [--color|--nocolor] [--amend] [--verbose] [--untracked]
-
-
-DESCRIPTION
------------
-Examines paths in the working tree that has changes unrecorded
-to the index file, and changes between the index file and the
-current HEAD commit.  The former paths are what you _could_
-commit by running 'git add' (or 'git rm' if you are deleting) before running 'git
-commit', and the latter paths are what you _would_ commit by
-running 'git commit'.
-
-If there is no path that is different between the index file and
-the current HEAD commit, the command exits with non-zero status.
-
-Note that this is _not_ the user level command you would want to
-run from the command line.  Use 'git-status' instead.
-
-
-OPTIONS
--------
---color::
-	Show colored status, highlighting modified file names.
-
---nocolor::
-	Turn off coloring.
-
---amend::
-	Show status based on HEAD^1, not HEAD, i.e. show what
-	'git-commit --amend' would do.
-
---verbose::
-	Show unified diff of all file changes.
-
---untracked::
-	Show files in untracked directories, too.  Without this
-	option only its name and a trailing slash are displayed
-	for each untracked directory.
-
-
-OUTPUT
-------
-The output from this command is designed to be used as a commit
-template comments, and all the output lines are prefixed with '#'.
-
-
-Author
-------
-Originally written by Linus Torvalds <torvalds@osdl.org> as part
-of git-commit, and later rewritten in C by Jeff King.
-
-Documentation
---------------
-Documentation by David Greaves, Junio C Hamano and the git-list <git@vger.kernel.org>.
-
-GIT
----
-Part of the gitlink:git[7] suite
