Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
revset: build _syminitletters from a saner source: the string module For now, these sets will be unicode characters in Python 3, which is probably wrong, but it un-blocks importing the module so we can get further along. In the future we'll have to come up with a reasonable encoding strategy for revsets in Python 3. This patch was originally pair-programmed with Martijn.
