Well, normalize_posix_path() (in path.cc) already scans the whole path
string looking for '\\' -- I can't imagine that adding a check for ':'
would introduce all that much overhead.  But, of course, empirical
evidence is always best, and I don't have any at the moment.

Eric, care to simply add a test for ':' in that loop and do some
measurements?
