First, I thought: wow!  How can that possibly work?  These guys are geniuses!

Then I found out that git-merge-subtree is a git builtin, and git.c says this:

  { "merge-recursive", cmd_merge_recursive, RUN_SETUP | NEED_WORK_TREE },
  { "merge-subtree", cmd_merge_recursive, RUN_SETUP | NEED_WORK_TREE },

And then my head exploded. :)

Still scraping the pieces of my brain back off the floor... but does
this mean the subtree merge strategy would fail exactly like
merge-recursive when new files are created?

Have fun,
