Hi, Emacs!
There doesn't seem to be a function `narrowedp'. This is, perhaps, an
unfortunate lack.
It's easy enough to test the lower bound:
(eq (point-min) 1)
, but the upper bound is a touch tedious:
(save-restriction
(let ((reg-end (point-max)))
(widen)
(eq reg-end (point-max))))
. Actually, I really just want to test the lower bound (to know whether
to need to test for point-min being inside a literal). But testing
point-min against "1" seems a bit unemacsy and unfutureproof. When
Emacs gets good multi-major-mode facilities, the "beginning of buffer"
will not be 1, rather the beginning of the particular buffer part. Or
something like that.
