This caused at least a regression in tab order which causes all my edits to fail:
1) Click "edit"
2) Hit "tab" to tab into edit field
3) Type something
4) Hit "tab" to tab into the comment field
5) Hit "enter" to save
Hey wait a minute, where's my edit?
When I go back and do it over, I find that I get tabbed from the edit box to the *cancel link*, so hitting enter goes back to the view page, destroying my edit.
Not good. :(

Haven't checked for other regressions; please be *very* careful with this edit page work, as seemingly small breakages can really damage the user experience and make things really badly broken.
Maybe we need a fuller UI test suite...
