parse-options: drop leading space from '--git-completion-helper' output

Browse Source 
The output of 'git <cmd> --git-completion-helper' always starts with a
space, e.g.:

  $ git config --git-completion-helper
   --global --system --local [...]

This doesn't matter for the completion script, because field splitting
discards that space anyway.

However, later patches in this series will teach parse-options to
handle subcommands, and subcommands will be included in the completion
helper output as well.  This will make the loop printing options (and
subcommands) a tad more complex, so I wanted to test the result.  The
test would have to account for the presence of that leading space,
which bugged my OCD, so let's get rid of it.
