Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Let app set SDL_VIDEO_ALLOW_SCREENSAVER environment variable to override SDL's attempt to disable screen savers. Works for Quartz (Mac OS X) and X11. Need a formal API for this in 1.3, still. Fixes Bugzilla #415.
