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.

# Ensure that tail does not ignore data that is appended to a tailed-forever
|
|
# file between tail's initial read-to-EOF, and when the inotify watches
|
|
# are established in tail_forever_inotify. That data could be ignored
|
|
# indefinitely if no *other* data is appended, but it would be printed as
|
|
# soon as any additional appended data is detected.
