parallel-tests: avoid trailing backslashes in make recipes The new testsuite-harness could generate recipes with a trailing backslash character (possibly followed by blank characters only), in the very common case where the user hadn't defined the special $(AM_TESTS_FD_REDIRECT) variable. This caused spurious syntax errors with at least older bash versions (e.g., bash 2.05b), and could be potentially unportable to other weaker shells. See automake bug#10436: <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10436> and coreutils bug#10427: <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10427#8> * lib/am/check2.am: Rework line breaks so that no backslash can be at the end of a line. * tests/parallel-tests-trailing-bslash.test: New test. * tests/list-of-tests.mk: Add it. Report and diagnosis by Paul Eggert.
