Um, I guess by "type" I meant something more like `:type' in the broader
"describing the shape of some field" sense. Not so much (info "(elisp)
Lisp Data Types") or what have you. Apologies for the confusion.

Poor choice of descriptive label on my part, clearly. I didn't mean to
suggest a custom user option but rather something like a
NIL-OR-NONEMPTY-STRING. IOW, whatever might satisfy a `typep' spec of

  '(cons symbol (or null (and string (not (string 0)))))

or similar (bastardized pseudo-CL notwithstanding).

The releases on ELPA are basically snapshots of lisp/erc taken whenever
the ";; Version: " header changes. So, the work you see on HEAD is still
unreleased. It's possible that incrementing the version ahead of time
(like to 5.5-git or something) would make that clearer, but AFAIK we
can't do that without triggering yet another release. Hope that makes
sense.
