A couple of optimizations are done in this PR. One, we now will check config ahead of time to see if a module is disabled before running any module code. Also, we won't try to discover a git repository unless the module requests access to it.
MacOS wc has a habit of leaving nasty spaces in the output, which was
messing up our argparser.
To fix, quote the output from the jobs command, then have Rust trim out
whitespace in the jobs module before parsing.
