To Artifact [a2f98072f0]:
- File mod/kcli/usage.fn.c — part of check-in [6aeac330ce] at 2020-01-31 05:58:38 on branch trunk — Add a final terminating null to first message in kcli_usage. This was causing the shared library build to segfault. Not perfect, as if there are no options, there will be two nulls, but two is better than none.
