        * regex.c (PATFETCH): Remove the translating fetch.
        (PATFETCH_RAW): Rename to PATFETCH.
        (set_image_of_range): New fun.
        (SET_RANGE_TABLE_WORK_AREA): Use it.
        (regex_compile): Don't translate the pattern chars so eagerly.
        Only do it when inserting an `exactn' bytecode or when handling
        a char-range.
        (mutually_exclusive_p): Avoid empty statement.

No, only in non-ASCII chars.  The excess is introduced in set_image_of_range
which is only used for non-ASCII chars.
