Not only this shrinks the size of the generated Makefile (from > 6300 lines to ~3000), but will allow further simplifications in future changes. * tests/Makefile.am (TEST_EXTENSIONS): Add '.sh' and '.pl'. (PL_LOG_COMPILER, SH_LOG_COMPILER): New, still defined simply to $(LOG_COMPILER) for the time being. (TESTS, root_tests): Adjust as described. * All tests: Rename as described.
