[PATCH 0/25] Usage message clean-up

This patch series is supposed to clean-up usage strings in *.sh and
*.perl. I have gone through most of the scripts, but have left the
following programs for various reasons.

No obvious fix:
  git-log.sh
  git-parse-remote.sh
  git-rebase.sh

Still todo:
  git-archimport.perl
  git-cvsexportcommit.perl
  git-cvsimport.perl
  git-svnimport.perl
  git-applymbox.sh
  git-applypatch.sh
  git-fmt-merge-msg.perl
  cmd-rename.sh
  git-ls-remote.sh
  git-merge-octopus.sh
  git-merge-one-file.sh
  git-merge-ours.sh
  git-merge-resolve.sh
  git-merge-stupid.sh
  git-octopus.sh
  git-parse-remote.sh



I have tried to follow the following rules:

* Any unrecognised options should make the script die with the usage
  message.
* -h and --help makes the script die with the usage message.
* The message is printed to stderr.
* The message is of the form "usage: $0 options"

I am not convinced that the last bullet point is the best way to do
things. Using "$0" is probably best for Git developers but using "git
program-name" is probably least confusing for users, especially if we
are going to move the git-* binaries away from /usr/bin. Another
option is "basename $0". What do you think?
