convert: fetch less revisions when looking for a branch parent

Test subversion branches conversion

convert: make svn revision iterator interruptible

convert: fix cross-branches subversion revisions handling The "one revision belongs to one branch" assumptions is relaxed. Branch revisions are parsed down to the first branch copy encountered, older history is skipped. It means the conversion is still not satisfying when dealing with branches overwriting themselves. This issue already existed in the previous version.

convert: fix parents of last fetched svn revision

convert: don't scan directories on property changes

hooks: fix pre- and post- hooks specified in .hg/hgrc We were looking up hooks in the wrong ui object. Also, we weren't handling hooks to commands without a repo.

[PATCH] zsh_completion tag/mq fixes Been using these for almost a month now without problems, so I figured some other people might want them. This allows the zsh completion to work with tags and mq patch names containing spaces, and adds support for qgoto.

tests: Use /bin/sh for test-journal-exists, /bin/bash may not be available

patchbomb: prompt only once for SMTP password - simplify mail._sendmail to be a function rather than a class - simplify connect to return a function rather than a class - move exception handling from mail.sendmail to mail.connect - use a single connection for all messages in patchbomb
