Brian Murray found a bug in my GreaseMonkey script for tagging Launchpad bugs. The issue was that if a Launchpad bug description had certain characters like &, +, >, <, then the description would be modified: +'s turned into spaces, &'s truncating the post... bad stuff.
Anyway, to fix just required unescaping the HTML retrieved *from* launchpad, to convert & to &, > to >, and so on, and also required using encodeURIComponent() instead of just encodeURI().
I've been finding this script *quite* handy for going through bunches of Launchpad bugs and assigning various tags to them. However, I also found that a handful of descriptions got buggered up due to &'s, and so this bug fix will make it a LOT easier to trust the script to do the right thing all the time.
