Subject: src/optparse.lisp: Don't print options which have no help text.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/sod/commitdiff_plain/88d1add260ad0eed008fa7559588c2cb2529bc7a?ds=inline

src/optparse.lisp: Don't print options which have no help text.

This seems better than crashing because nil isn't a thing that can have
characters extracted from it.
