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.
