Note that on Windows a remote with a path like /home/foo/bar is interpreted by git as being some screwy relative path (relative to what exactly seems ill-defined -- it seemed relative to C:\Program Files\Git\ in my tests!) So no attempt has been made to handle such a path sanely, just not to crash when encountering it. Note that "C:\\foo" </> "/home/foo/bar" yields /home/foo/bar even though that is not absolute! I don't know what to make of all this, except that I will be very happy when this crock of **** vanishes from the face of the earth.

{- git FilePath library
|
|
-
|
|
- Different git commands use different types of FilePaths to refer to
|
|
- files in the repository. Some commands use paths relative to the
|
|
- top of the repository even when run in a subdirectory. Adding some
|
|
- types helps keep that straight.
