  init.m4: add probe to check "rm -f" without args work
  
  See automake bug#10828.
  
  POSIX will say in a future version that running "rm -f" with no argument
  is OK: <http://austingroupbugs.net/view.php?id=542>).
  
  We want to be able to make that assumption in our Makefile recipes.
  So we introduce an aggressive probe to check that the usage we want is
  actually supported "in the wild" to an acceptable degree.
  
  * m4/init.m4 (AM_INIT_AUTOMAKE): Implement the probe.  To make any issue
  more visible, cause the running configure to be aborted by default if
  the 'rm' program in use doesn't match our expectations; the user can
  still override this though, by setting the ACCEPT_INFERIOR_RM_PROGRAM
  environment variable to "yes".
  
  * t/spy-rm.tap: Update heading comments.
  * t/rm-f-probe.sh: New test.
  * t/list-of-tests.mk: Add it.
  * PLANS/rm-f-without-args.txt: Adjust.
