I would prefer to catch the case in the compatibility layer. Here is

Subject: mingw: verify that paths are not mistaken for remote nicknames
This added test case simply verifies that users will not be bothered
with bogus complaints à la
warning: unable to access '.git/remotes/D:\repo': Invalid argument

[j6t: mark the new test as test_expect_failure]
