  * Fix amusing bug with .hat extensions.
     hat-stack abc     -> looked for file abc.hat
     hat-stack test    -> looked for file tes.hat
     hat-stack mat     -> looked for file m.hat
     hat-stack abchat  -> looked for file ab.hat
  
  I.e. the routine (rmext()) to find and remove an existing '.hat'
  extension was flawed.
