run-tests: fixed warn detection on failures with too many output
The state "warned" was reported too often. The problem fixed here is that
warnonly was only reset when a line did not match. When there was a line too
much, warnonly remained set.
Fix this by setting more states to warnonly.
More negative testing (testing on result "Failed") has been done this time.

# way such a file can be deleted or renamed on Windows (other than
# scheduling the delete or rename for the next reboot).

# posixfile (or comparable methods) will delay the actual deletion of
# the file for as long as the file is held open. The filename is blocked
# during that time and cannot be used for recreating a new file under
# that same name ("zombie file"). Directories containing such zombie files
# cannot be removed or moved.
# A file that has been opened with posixfile can be renamed, so we rename

# callers to recreate f immediately while having other readers do their
