The technical obstacle is that `locale', the fall-back value, isn't
available outside set-locale-environment (AFAICS).

I had assumed that `set-locale-environment' runs before processing of
customization options, and by experiment this is the case.

LC_MESSAGES=en_US emacs --no-site-file
  -> woman-locale = en_US.ISO8859-1

Customize woman-locale to nil, save and exit

LC_MESSAGES=en_US emacs --no-site-file
  -> woman-locale = nil

Arguably that is what should happen.

I see what you're saying and perhaps you're right. There could be a
general locale variable which woman should use, unless woman-locale is
non-nil, in which case it should be preferred.

But AFAICS there is no such general locale variable at present (no
Lisp variable, including system-messages-locale, seems to be set based
on LC_MESSAGES), so I'd have to add one, which would only be used
by... woman.
