bug#36107: Global Buttons Stop Functioning When Current Working Directory Changes (Forgot the Subject!)

[Robert Weiner]

hypb:functionp is defined in the hypb.el file in the Hyperbole directory or:

"${hyperb:dir}/hypb.el"

Hmm. I followed the instructions, and still have the error.

I went looking for `hypb:functionp` and didn't find anything either --
though, obvs, I don't know the codebase, so it could be defined
somewhere non-obvious, or I may be totally missing something. Doesn't
come up in {M-x describe-function}, wasn't listed in
`hyperbole-autoloads.el`, and didn't turn up when I searched in the code
directory with `ag`.

I've been doing this testing on my normal init, but it doesn't come up
in a vanilla Emacs with just Hyperbole loaded either.
