Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fixing #225; for some reason MySQL finds the user 'John' when searching for 'John ' (note trailing space). This doesn't happen on SQLite. This causes a NoReverseMatch when searching for 'John ' in the member search. The solution is to call strip() on the form field contents in the clean_username() method of the search form.
