Revert lots of half-finished local debris I didn't mean to check in with Isaac's roadmap update.
Mercurial's "import" command is still broken, committing local tree changes to files that weren't even touched by the patch because the hg developers inisist, when I point out how stupid it is, that they meant to do that. (hg record can do hunks, but import can't even track _files_.)
