Subject: Minor bug, git ls-files -o aborts because of broken submodules
Message-ID: <CACsJy8BpCc6sNKUs3TsMnA_8dk+uFvZy1T_UmfQMxcm2bpg2uw@mail.gmail.com>

$ git init abc
$ cd abc
$ mkdir def
$ echo 'gitdir: blah blah' >def/.git
$ git ls-files -o
fatal: Not a git repository: def/blah blah

If some directory looks like a submodule but turns out not, that's not
a fatal error. The stack trace is something like this. I suspect
do_submodule_path should use the gently version..
