[PATCH 2/2] Windows: do not treat a path with backslashes as a remote's nick name

Fetching from a remote using a native Windows path produces these warnings:
C:\Temp\gittest>git fetch C:\Temp\gittest
warning: unable to access '.git/remotes/C:\Temp\gittest': Invalid argument
warning: unable to access '.git/branches/C:\Temp\gittest': Invalid argument
From C:\Temp\gittest
 * branch            HEAD       -> FETCH_HEAD

The functions that read the branches and remotes files are protected by a valid_remote_nick() check. Its implementation does not take Windows paths into account, so that the caller simply concatenates the paths, leading to the error seen above.

Use is_dir_sep() to check for both slashes and backslashes on Windows.
