Subject: bug#20146: font-lock-extend-jit-lock-region-after-change: results are discarded instead of being returned.
Date: Thu, 19 Mar 2015 23:01:36 +0000 [thread overview]
Message-ID: <20150319230136.GC2753@acm.fritz.box> (raw)
Hi, Emacs
In font-lock-extend-jit-lock-region-after-change in font-lock.el, the
new fontification region is calculated by funcalling
font-lock-extend-after-change-region-function. The result of this
funcall is assigned to internal variables beg and end.
To return these values to the caller, they should be written to the
dynamically bound variables jit-lock-start and jit-lock-end. This is
only done in the case
(memq 'font-lock-extend-region-wholelines
font-lock-extend-region-functions)
. It should be done in all cases.
