  warnings: fix buglets for portability warnings
  
  * lib/Automake/ChannelDefs.pm (switch_warning): Ensure the
  correct implications and inter-dependencies between warnings
  in the categories `portability', `extra-portability' and
  `recursive-portability' are respected.  Also add detailed
  explicative comments, and references to the relevant tests.
  * tests/dollarvar2.test: Update and extend.  Also, remove
  some unnecessary uses of `--force' option in automake calls.
  * tests/extra-portability3.test: New test.
  * tests/Makefile.am (TESTS): Add it.
