Patch Set 2: I would prefer that you didn't submit this; No score

fix typos in commit message:

GIT_CEILING_DIRECTORIES
A colon (semicolon on Windows) separated list of paths
which JGit will not cross when looking for the .git directory.

the following test fails during tear down on Windows (I'll debug into that later):
