  python: restore more compatible behavior for $PYTHON.
  
  For https://bugs.gnu.org/74434.
  
  * lib/py-compile: if $PYTHON -V does not include the
  string "python" (case-insensitive), consider the support
  intentionally disabled and exit successfully, unless PYTHON is set
  to false, in which case exit unsuccessfully. This is closer to
  the old behavior. Mention this in the help message.
  * t/py-compile-env.sh: add test for PYTHON=:.
  * NEWS: mention this. (And, en passant, add some past bug#s and
  clarify that only RCS/SCCS pattern rules were disabled, not all.)
