revset: support raw string literals
This adds support for r'...' and r"..." as string literals. Strings
with the "r" prefix will not have their escape characters interpreted.
This is especially useful for grep(), where, with regular string
literals, \number is interpreted as an octal escape code, and \b is
interpreted as the backspace character (\x08).
