git's use of mkdir(2)

I've been trying to convince git to run on some of the systems I use.
Of particular relevance at the moment are two BSD systems which have an
important behavioural difference.

Specifically, if /foo/bar does not exist but /foo does,
mkdir("/foo/bar/",...) works on one and fails showing ENOENT on the
other.  (Without the trailing slash, it works on both.)

git (at least in the version I've got here, which appears to be
1.6.4.1) depends on this working, and breaks as a result on the second
of the above two systems.

I've been doing a little digging and I think I might be able to fix
this - but, before I charged ahead with it, I thought I'd float a query
here to ask (a) if this is a known issue and fixed in something more
recent (I had a look at 1.7.2 and a quick read of the code makes me
think it still does this, but I could have missed something) and (b) if
there would be any interest in such fixes if I do come up with them.

Thoughts?
