__git_complete_file()'s job is to complete the '<rev>:<path>' notation,
e.g. 'master:Mak<TAB>',  which is not what we want here, because this
notation doesn't make sense for 'git status' and because 'git status
<TAB>' would then offer refs instead of files.

I think there are two choices what to do instead:

   - Don't do anything :)  Bash will then fall back to filename
     completion, which is quite close to what we want here (and in this
     case the return statements from the other case arms can go away as
     well).  The drawback is that all ignored files in the current
     working directory will show up after 'git status <TAB>'.

   - use __git_complete_index_file() with appropriate options, perhaps
     '--cached --others', but I didn't think this through.  For bonus
     points pass additional options when certain 'git status' options are
     already present on the command line, e.g. pass '--ignored', too, if
     it is present.
