annotate svncommands.py @ 284:f8f9a2993705

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Implement parseurl support (#revision in repository urls) Note: Normally when using parseurl, hg clone will treat the revision after # as if it was passed in as --rev, treats that rev as a head and won't clone beyond that. This wasn't implemented here, hence all the TODO's in the comments. All we do is use the checkout parameter where appropriate to update the wc to the selected revision.
