} I see that the setlocale code is a bit meatier than I would have expected.

I am mostly concerned about things like re-opening (or worse, reading) of
external locale-definition files.

} I'm also beginning to wonder if prev_locale won't get clobbered somehow.

Oo, ick.

} On sheer byte count or by some other criterion?

(1) That it's more likely to be supported correctly, and (2) that it is
after all C-like expression parsing that math.c is attempting to peform.

It further occurs to me that it might be bad even to have output formatting
controlled by LC_NUMERIC, given the tendency of scripts to do things like

	eval $(print ...)

Where *exactly* would LC_NUMERIC make any difference in pws-9 ?
