Message : Clean up xkb_sym_interpret a bit First we split the LEVEL_ONE_ONLY bit off of the 'match' field, which allows us to turn enum xkb_match_operation to a simple enum and remove the need for MATCH_OP_MASK. Next we rename 'act' to 'action', because we've settled on that everywhere else. Finally, SIMatchText is changed to not handle illegal values - it shouldn't get any. This removes one usage of the GetBuffer hack. Signed-off-by: Ran Benita <ran234@gmail.com>
