When we use the PREMIRROR/MIRROR from the local disk, and if it is in a
deep directory, for example, when len(path) > 255 (The NAME_MAX), we
will get the "filename too long error".

This is becuase we use ud.path.replace('/', '.') to change the path to
the filename. We seldom see such a long url, but it is easy to produce
it on the local machine.

Another problem is that:


will be converted into .local.path whichi is a hidden file by default.

Don't convert the name when ud.proto == "file" will fix the problem.

- This is only for git, other fetchers also have the similar problem,
  will send the patch for others if this is fine.

- Another solution might be: use the md5sum(path) as part of the
  filename, I'm not sure whether it is worth.
