I'm surprised that such a function doesn't (yet) exist in Emacs...
But until such a function exists, one might want to consider the
following:
1. Adding expand-file-name will work for any file name that
cygwin-mount is designed to address (this is by definition)
2. Similarly, adding expand-file-name will likely work for any other
Magic File handler that works similar to cygwin-mount in terms of
just converting paths but generally won't work with Magic File
handlers that work on archives or compressed file formats
3. Adding expand-file-name shouldn't have any ill effect on paths that
are not Magic files
To take account of the fact that expand-file-name may not give a valid
OS path for all Magic File handlers, I would suggest the following
slight modification to my originally suggested patch.
Basically, this version does 2 things:
1. Pre-expands the file name *if* there is a Magic File handler for that
file path (this will do nothing if there is no handler for that path)
2. Tests file-exists-p with all Magic File handlers shut off which
tests to make sure that the OS primitives will work on the actual
file path that will be passed
