Subject: test_main: Add option to list tests
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8295366f9412b578a382a34ae360581d63269656;p=thirdparty%2Flibarchive.git

test_main: Add option to list tests

The test runner already lists available tests if it fails to parse the
command line, but add a -l option to explicitly do this without also
printing an error message and a summary of options.
