I inherited this .emacs file from someone else who had this set. I'm guessing it used to be customizable? If it really isn't proper to customize it this way thats fine. I can disable it with no real issues. I can just change the regexps I am using in font-lock-add-keywords. I assumed that it could be customized because if I did a search the customize option for it showed up, but maybe improperly setting it with custom-set-variables just adds it to Customize.

I inherited this .emacs file from someone else who had this
set. I= 'm guessing it used to be customizable? If it really isn't
prope= r to customize it this way thats fine. I can disable it with
no real iss= ues. I can just change the regexps I am using in
font-lock-add-keywords.= I assumed that it could be customized
because if I did a search the cus= tomize option for it showed up,
but maybe improperly setting it with cus= tom-set-variables just
adds it to Customize.

How did you end up with that?
font-lock-keywords-case-fold-search is not a customize variable, so you
should not set it with custom-set-variables.

Clearly not a desirable behavior, indeed, but the above var setting is
clearly a pilot error.=C2=A0 Of course

=C2=A0 =C2=A0 (setq-default font-lock-keywords-case-fold-search t)

would give the same result, but I'd also argue that it'd be
a pilot error.


=C2=A0 =C2=A0 =C2=A0 =C2=A0 Stefan
