Subject: [PATCHv2 13/21] completion: don't offer commands when 'git --opt' needs an argument

From: SZEDER Gábor <[email-masked]>
Date: Fri, 3 Feb 2017 03:48:21 +0100

The main git options '--git-dir', '-c', '-C', '--worktree' and
'--namespace' require an argument, but attempting completion right
after them lists git commands.

Don't offer anything right after these options, thus let Bash fall
back to filename completion, because

  - the three options '--git-dir', '-C' and '--worktree' do actually
    require a path argument, and

  - we don't complete the required argument of '-c' and '--namespace',
    and in that case the "standard" behavior of our completion script
    is to not offer anything, but fall back to filename completion.
