Fix 'clone' failure at DOS root directory.
Cloning via relative path fails for a project residing immediately under the root directory of a DOS drive. For instance, for project c:/foo, issuing "cd c:/" followed by "git clone foo bar" fails with error "Unable to find remote helper for 'c'". The problem is caused by make_nonrelative_path() incorrectly returning c://foo rather than c:/foo for input "foo". The bogus path c://foo is misinterpreted by transport_get() as a URL with unrecognized protocol "c", hence the missing remote helper error. Fix make_nonrelative_path() to return c:/foo rather than c://foo (and /foo rather than //foo on Unix).
