Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix whitespace Use a consistent standard - Tabs in front for indenting, spaces after for anything else. This way everything stays nice and lined up while also letting users change there prefered indent level. Most of the new files from Haata where already in this format.
