+       tests: tweak few tests on simple and parallel test drivers
+       * tests/check-exported-srcdir.test: Improve heading comments.
+       * tests/check-tests-in-builddir.test: Likewise.  Also, unset the
+       `FOO_EXIT_STATUS' variable, so that any pre-existing value in the
+       environment won't risk to interfere with the test.
+       Suggestions by Ralf Wildenhues.

 +      python: extend and improve tests, fix minor glitches
 +      * m4/python.m4 (AM_PATH_PYTHON): Ensure the "checking ..." messages
 +      from configure are always complete, even in case of failure.  Tiny
 +      cosmetic improvement in info/error messages.
 +      * tests/python.test: Also check that automake complains if the
 +      PYTHON primary is used but the `py-compile' script is not present.
 +      Make grepping of generated Makefile.in laxer w.r.t. whitespace.
 +      Add trailing `:' command.
 +      * tests/python2.test: Remove repeated calls aclocal: they are
 +      useless because configure.in is never modified.  Make grepping
 +      of automake stderr more comprehensive.  Remove the pre-existing
 +      `py-compile' file before trying to install it with `--add-missing'.
 +      Add trailing `:' command.
 +      * tests/python3.test: Add trailing `:' command.
 +      * tests/python11.test: Likewise.
 +      * tests/python4.test: Likewise.  Also, try to pass PYTHON config
 +      variable to configure from the environment, rather than only from
 +      the command line.
 +      * tests/python5.test: Ensure that the "checking ..." messages from
 +      configure are always complete.  Use proper m4 quoting.  Add a
 +      trailing `:' command.
 +      * tests/python6.test: Simplify test logic, by checking for files
 +      created by configure rather then grepping its output.
 +      * tests/python7.test: Likewise.
 +      * tests/python8.test: Also check that `$PYTHON' is meaningfully
 +      set in the ACTION-IF-TRUE argument of AM_PATH_PYTHON.
 +      * tests/python9.test: Likewise.
 +      * tests/python10.test: Add trailing `:' command.
 +      (Makefile.am): Declare `disttest' target as `.PHONY', and add
 +      an `ls -l' to its recipe, for debugging.
 +      * tests/nobase-python.test: In testing "make uninstall" and
 +      "make install" results, prefer idioms that make verbose logs
 +      more helpful.  Remove a couple of lines of dead code.  Add a
 +      trailing `:' command.
 +      * tests/python5b.test: New test, checking that configure performs
 +      the check on the python version even when the choice of the python
 +      interpreter is forced by the user.
 +      * tests/python-dist.test: New test, checking the distribution of
 +      *_PYTHON files.
 +      * tests/python-vars.test: New test, checking that AM_PATH_PYTHON
 +      correctly set all the output variables advertised in the manual.
 +      * tests/python-virtualenv.test: New test, checking that python
 +      support offered by automake works well with "virtual python
 +      environments" created by the `virtualenv' program.
 +      * tests/instdir-prog.test: Also check `$(pyexecdir)'.  Existing
 +      checks made slightly stricter.
 +      * tests/instdir-prog.test: Also check `$(pyexecdir)'.  Existing
 +      * tests/instdir-ltlib.test: Likewise.
 +      * tests/Makefile.am (TESTS): Update.
