Improved auto-linkification patch.
FYI, timwi's improved auto-linkification patch is now live on the site. (Though it might take a bit to propagate to all the servers; I don't really know how that stuff works.)
So we no longer need to worry about following links with periods (full stops) in FAQ.
(Also in support, probably, though there is the argument that this patch won't affect e-mail clients.)
