-- Vin Shelton <acs(a)alumni.princeton.edu> spake thusly:
I'm likely to just switch back to 21.1.12 for right now since
21.4.6
also has an annoying performance regression when deleting text out of
a font-lock buffer, but I'm curious whether anyone else is seeing
this one or if it's something peculiar to my configuration.
Is it possible to provide any further details on this? Can you generate
a -vanilla recipe for reproducing it? I haven't seen anything like this
and I'd love to get all these issues fixed.
