Moved --cwd handling in front of -R handling again. Shorter code for initial -R.

Make hg paths and hg debugconfig work with -R/--repository option. Commands that can use a repo, but don't need one, should be added to the "optionalrepo" string, similar to the "norepo" string.

Always try to open the repository if -R/--repository is specified. This makes 'hg -R something_unknown command' consistently fail for all commands, not only for those who need a repository.

Make bisect extension work with python2.3

Fixed spacing/indentation, removed #! script header, added short description.

Fixed contrib/hbisect.py to work with the new opener behaviour.

Fix some problems when working on broken repositories: Fix tracebacks in hg verify for certain repo errors. Print compression type byte encoded safely.

Fix mq's usage of opener, which don't allow absolute paths now.

merge with crew

Hide debug commands in ambiguous command list, unless no normal command matches. This will execute diff if 'hg d' is typed and hide rawcommit on 'hg r'. Based on a patch by TK Soh.

Show ambiguous aliases, if they are not simple abbreviations. Sort output.

show choices on ambiguous commands

fix annotate for removed files walk in the manifest files instead of the working dir files when running annotate

only put numbers on patches if > 1 patch.

Patchbomb only sends introductory message [0 of N] if there are multiple patches.
