[WIP PATCH 00/10] Work-in-progress merge-recursive work

This is a set of changes I was working on last Sept-Nov; these changes are not ready for git.git (other than perhaps patches 1 and 5), but I figured it might be useful to send anyway because (1) it might serve as notification to others of various edge and corner case issues that exist, and (2) the work won't die if my laptop harddrive does.

I'm expecting to clean these up, though it may take me a month or two before I get the time.

(Note that patch 5 contains a subset of b9b3eef (merge-recursive: tweak magic band-aid 2011-03-17); I could have saved Junio some time if I had submitted that earlier, and had remembered that change instead of propagating the mistake. Sorry about that.)

Most of what is included are new testcases exposing edge and corner case bugs in merge-recursive that I found in a code audit, some of which are marked as test_expect_success even though the test does not succeed. There may be a few tests that are just cases I was testing for completeness or that I was worried about breaking with planned changes. I didn't try to figure out the right place to add all these tests (we're out of space in the t60[23]x range and I wasn't sure if I wanted to dump all of these into t6036), so I just named them tempxx.sh.
