  Log:
  SVN rev 213814 on 2010-10-13 23:29:09Z by obrien
  
  Do not assume in growstackstr() that a "precious" character will be
  immediately written into the stack after the call.  Instead let the caller
  manage the "space left".
  
  Previously, growstackstr()'s assumption causes problems with STACKSTRNUL()
  where we want to be able to turn a stack into a C string, and later
  pretend the NUL is not there.
  
  This fixes a bug in STACKSTRNUL() (that grew the stack) where:
  1. STADJUST() called after a STACKSTRNUL() results in an improper adjust.
     This can be seen in ${var%pattern} and ${var%%pattern} evaluation.
  2. Memory leak in STPUTC() called after a STACKSTRNUL().
