* Add insane double encode/decode to utf8 around call to markdown.
This works around a truely strange bug, which is apparently a bug in
- perl, which I lack space to describe here (see t/crazy-badass-perl-bug.t)
+ perl, #376329. Also added a test case for it.
* Improve layout of edit page so formatting help link is always visible w/o
getting in the way of the preview.
