RFR: 1274: The help message of the 'git-pr' sub-commamd misses the sub-command name

[Guoxiong Li]

Hi all,

This little patch fixes the help message when using the `git-pr` sub-command. For example:

Before this patch:


$ git-pr list -h

usage: git-pr [options] [<ID>] // <---- Here miss the `list`
      // Ignore the following output.


After this patch:


$ git-pr list -h
usage: git-pr list [options] [<ID>]
      // Ignore the following output.


Thanks for taking the time to review.

Best Regards,
-- Guoxiong
