recur status on linux-2.6

Hi,

I tested git-merge-recur vs. git-merge-recursive on the linux-2.6 repository last night. It contains 2298 two-head merges. _All_ of them come out identically with -recur as compared to -recursive (looking at the resulting index only).

That was the good news. The bad news is: it _seems_, that -recur is only about 6x faster than -recursive, not 10x, and this number becomes smaller, the longer the merge takes. So I see a startup effect here, probably.

Ciao, Dscho
