From 60edcd04e52323050792252009512f7592f3b66c Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Sun, 3 Oct 2010 21:51:45 +0200 Subject: Make external links in comments clickable (FS#20137). Comments are now split at link boundaries and links are converted separately. I find this to be a much cleaner way than re-converting comments that have already been converted using htmlspecialchars(). This also doesn't require any callback procedure.
