[PATCH] Allow 'git cmd -h' outside of repository

Printing usage strings of git commands should obviously not depend on
the command being run inside a git repository.  However, in case of a
command requiring a repository, the command line options are parsed only
after it is ensured that the command was started inside a repository,
resulting in a 'fatal: Not a git repository' if 'git cmd -h' wasn't
executed inside a repository.

To get around this issue, we will check early for the presence of '-h'
option, and skip ensuring that the command is run inside a repository.
