[PATCH] fix t1504 on Windows

The test t1504 crashes on Windows due to a failed assertion in normalize_absolute_path() because this function expects absolute paths to start with a slash, while on Windows they can start with a drive letter or a backslash.

As suggested by Johannes, fix it by using sanitary_path_copy() instead, which can handle Windows-style paths just fine. This patch just exports it for usage; a later patch may move it from setup.c to path.c where it fits better.

Secondly, use the portability macro PATH_SEP instead of expecting colons to be used as path list delimiter. On Windows, semicolons are used, while colons separate drive letter and path.

Also change the test script to help bash recognize the path list variable for test case "first_of_two" as needing path conversion. git expects Windows-style paths, which bash happily creates if we turn the second path of the list into an absolute one.
