[bug] 2.39.0: error in help for ls-remote

[Jeremy Hetzler <jeremyhetzler@gmail.com>]

All,

The short help for ls-remote advertises that '-h' is short for '--heads':

> usage: git ls-remote [--heads] [--tags] [--refs] [--upload-pack=<exec>]
>                      [-q | --quiet] [--exit-code] [--get-url] [--sort=<key>]
>                      [--symref] [<repository> [<refs>...]]
>

>     -t, --tags            limit to tags
>     -h, --heads           limit to heads
>     --refs                do not show peeled tags

However, 'git ls-remote -h' instead prints the help. So perhaps the
help message should be revised.

git version 2.39.0
