​You're right about woman being designed to run without man, I hadn't
thought of that.

There's nothing wrong with woman-manpath's built-in database. The idea is
simply to use "manpath"'s extra functionality, which looks for man pages in
directories formed from the directories on PATH.

I guess the logical thing to do would therefore be to replicate this
functionality directly, but I don't propose to do it.​

​I explained  that: man -k does not support man directories lacking a
database.

I've fixed that for my own purposes by running "mandb" as a per-user
cronjob, so I suggest you can ignore this patch (which I agree is
ill-conceived), and close the bug report.

Thanks as always for your penetrating analysis.
