[FYI] {master} check: fix test-suite.log formatting with NetBSD sed

[Stefano Lattarini]

* lib/am/check.am (am__rst_section): Tweak to ensure en extra final
newline is printed also with NetBSD sed.  Issue revealed by a
failure of 'test-metadata-global-result.test'.
* tests/rst-formatting.test: New test, checking the internal
variables '$(am__rst_title)' and '$(am__rst_section)'.
* tests/list-of-tests.mk: Add it.
