hack/bats: fix broken usage message
I am so, so sorry.
###############################################################################
# BEGIN usage message
-usage="Usage: $0 [--root] [--rootless] [--filter=filename[:testname]]
+usage="Usage: $0 [--root] [--rootless] [FILENAME-PATTERN[:TEST-PATTERN]]
$0 is a wrapper for invoking podman system tests.
--root Run only as root
--rootless Run only as user (i.e. you)
- --filter=name Run only test files that match 'test/system/*name*',
+ FILENAME-PATTERN Run only test files that match 'test/system/*name*',
e.g. '500' or 'net' will match 500-networking.bats.
- If ':pattern' is appended, and you have a modern-enough
- version of bats installed, runs with '--filter pattern'
- which runs only subtests that match 'pattern'
+
+ TEST-PATTERN When appended to a filename-pattern, and you have a
+ modern-enough version of bats installed (i.e. Fedora
+ but not RHEL), runs with '--filter TEST-PATTERN' which
+ runs only subtests within FILENAME-PATTERH whose names
+ match that string.
-T Passed on to bats, which will then show timing data
