A user came into #emacs today complaining that his paren matching was not working with a large file, and that font-locking broke as a result. I found that this is controlled by blink-matching-paren-distance, which was increased to 25kb around 1997. Attached is a patch which doubles this to 50kb, as this should be fine for modern machines. I think that we should seriously consider setting the default to nil, but this seems like a more conservative approach to the matter.
