/* This is needed because web2c turns the Pascal construct 'x' into the
   C character constant 'x', not the string "x". And we need to keep it
   that way because that's how xord is initialized, etc.  But sometimes
   we want one-character strings -- e.g., in tangle.ch and weave.ch.
   There's no real alternative to wasting the two bytes of memory (plus
   malloc overhead) here, but it doesn't matter.  */
