[Bug 1317154] Re: autocompletion for 'git submodule' commands is broken

[Axel Beckert]

Can't reproduce this in Debian Unstable with zsh 5.0.5-2, hence this is
likely fixed already and an update of Ubuntu's zsh package to 5.0.5-2
should fix it in Ubuntu, too.

Title:
  autocompletion for 'git submodule' commands is broken

Status in “zsh” package in Ubuntu:
  Fix Committed

Bug description:
  Autocompletion in bash for subomdules works by completing simple file
  paths.

      $ git clone https://gerrit.googlesource.com/gerrit && cd gerrit
      $ git submodule init plugins/<TAB><TAB>
      commit-message-length-validator/ README                           reviewnotes/                     
      helloworld/                      replication/  

  In zsh the completion tries to be clever and list the submodule names
  only.  But it collects too much information and tries to complete
  submodule name + commit description.  So, I expect this:

      % git submodule init plugins/<TAB>
      plugins/commit-message-length-validator plugins/reviewnotes
      plugins/replication

  Instead I get this:

      % git submodule init plugins/<TAB>
      plugins/commit-message-length-validator\ \(v1.0-rc1-9-g545000b\)  plugins/reviewnotes\ \(v1.0-rc1-8-ge984300\)
      plugins/replication\ \(v1.1-rc0-13-g4c3f4c9\)   

  If I use --noglobalrcs I get the bash-style simple pathname behavior:

      $ zsh --noglobalrcs
      % git submodule init plugins/<TAB>
      commit-message-length-validator/  README                            reviewnotes/                      
      helloworld/                       replication/            

  I believe this bug is new in 14.04.  I did not see it until I updated from 13.10 to 14.04.
  I tried different versions of git (going back to 1.7.6) and the bug persisted.  I did not try different versions of zsh.
