Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Merged unicode-support back into trunk. Now all GUI/visible strings should be unicode. Internal strings unchanged. Remember to use a font that actually has the desired codepoints. Current default unicode policiy is 'ignore'.
