[issue1940] bdiff can sometimes create a stack overflow

[Alistair Bell]

New submission from Alistair Bell <mercurial at bellsonline.com>:

In converting a big Perforce repo to hg recently, I had to iron out a few
issues. One of them was that bdiff was giving me a stack overflow on some
big diffs. It looks like the developer of bdiff was expecting the compiler
to do tail-recursion optimization, and for whatever reason GCC 3.4.6 wasn't
doing it.

I converted the tail recursion to iteration, and everything worked. I'm
attaching a patch. (There's a little bonus patch in there too, to make
conversion from Perforce of filenames with spaces in them work.)
