bash: offer only paths after '--'

Many git commands use '--' to separate subcommands, options, and refs
from paths.  However, the programmable completion for several of these
commands does not respect the '--', and offer subcommands, options, or
refs after a '--', although only paths are permitted.  e.g. 'git bisect
-- <TAB>' offers subcommands, 'git log -- --<TAB>' offers options and
'git log -- git<TAB>' offers all gitgui tags.

The completion for the following commands share this wrong behaviour:
  am add bisect commit diff log reset shortlog submodule gitk.

To avoid this, we check the presence of a '--' on the command line first
and let the shell do filename completion, if one is found.
