  xpath.c: Changed all (?) occurences where validation macros
  (IS_xxx) had single-byte arguments to use IS_xxx_CH instead
  (e.g. IS_BLANK changed to IS_BLANK_CH).  This gets rid of
  many warning messages on certain platforms, and also high-
  lights places in the library which may need to be enhanced
  for proper UTF8 handling.
