Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Make 8 bit immediate operands flag a byte overflow if not in 8 bit range. 8 bit immediate operands should flag a byte overflow if they are out of range. The acceptable range is -128 <= x <= 255 to cover both signed and unsigned values.
