annotate stateview.c @ 103:a71544cd01ea

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Don't pre-emptively translate code at interrupt vectors as some PD ROMs have these pointing at junk. Need some kind of heuristic for detecting garbage if I'm going to translate them ahead of time by default.
