A non-empty line containing no spaces should be treated by --parseopt as
an option group header, but was causing a bus error. Also added a test
script for rev-parse --parseopt.

e.g.
% printf "foo\n--\noption-group-header\n" | git rev-parse --parseopt -- -h
Bus error
Wasn't sure whether to add the --parseopt test to t0040-parse-options.sh or
t1500-rev-parse.sh. I ended up creating a new test script. Hopefully calling
it out will increase the likelihood of it growing additional --parseopt tests.
