[PATCH] ignore trailing slash when creating leading directories

[Clemens Buchacher <drizzd@aon.at>]

'git clone <repo> path/' (note the trailing slash) fails, because the
entire path is interpreted as leading directories. So when mkdir tries to
create the actual path, it already exists.

This makes sure a trailing slash is ignored.
