The problem here is that the bash completion calls darcs trackdown
--list-options to find out what flags exist, but this command fails because
darcs trackdown itself may only be run in a repository.

So the fix is to make --list-options able to run (as is the case with
--help) even when in a situation where the command itself cannot be run.
This isn't entirely trivial, since some features (e.g. completing for pull
using the repositories in _darcs/prefs/repos) won't work if you aren't in a
repository. Still, this shouldn't be *too* hard to fix.
