Hi,

As of emacs-19.25, font-lock still takes Way Too Long to fontify Really Big
Files.  I haven't been able to discover a way to work around this.  If I
type C-g after about 10 seconds, the file load gets aborted, instead of the
fontification.  Once I have turned on the font-lock hook, whenever I load a
.c file, it must be fontified.

Shouldn't there be a way to tell font-lock to not fontify files that are
bigger than some user-settable size?

Also, the function font-lock-fontify-region would be good if I could have
the above-mentioned feature, but it would be better to have a function that
would just re-fontify some user-settable area around the current point (say
40 lines above and below the current line, for instance).

Any chance of getting this into font-lock?  I can't use font-lock as an
enticement to convert heathen into emacsen if they must wait 2 minutes
each time they want to browse a huge file.

thanks very much,
tw
