Less annoying directory completion (see http://bugs.debian.org/343458)
The current bash completion script is quite painful in conjuntion with
deep directory trees because it adds a space after each successful
directory completion. Eg. "hg clone /ho<tab>" is completed to "hg clone
/home " when what you really want is "hg clone /home/" (assuming the
complete path to the repository looks like /home/foo/hg...).
That's because the 'complete' command does not know about the type of
completion it receives from the _hg shell function. When only a single
completion is returned, it assumes completion is complete and tells
readline to add a trailing space. This behaviour is usually wanted, but
not in the case of directory completion.
I've attached a patch that circumvents this problem by only returning
successful completions for directories that contain a .hg subdirectory.
If no repositories are found, no completions are returned either, and
bash falls back to ordinary (filename) completion. I find this behaviour
a lot less annoying than the current one.
Alternative: Use option nospace for the 'complete' command and let _hg
itself take care of adding a trailing space where appropriate. That's a
far more intrusive change, though.
