Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Teach build to build only the toys/*.c selected in .config, and teach CFG_TOYSH_DEBUG to shut up the spurious "gcc can't tell that this is never actually used uninitialized because gcc is stupid" warnings.
