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.

# Demonstrate that when moving a symlink onto a hardlink-to-that-symlink, the
|
|
# source symlink is removed. Depending on your kernel (e.g., Linux, Solaris,
|
|
# but not NetBSD), prior to coreutils-8.16, the mv would successfully perform
|
|
# a no-op. I.e., surprisingly, mv s1 s2 would succeed, yet fail to remove s1.
