Tramp is *not* triggered by DOS file names.

Instead we see the following call chain:

describe-function => require(shortdoc) =>
file-remote-p("/ssh:user@host:/tmp/foo") =>
error: (void-function "get-process")

The call of file-remote-p in shortdoc is triggered by Tramp's
integration there. It should be harmless (always returning if Tramp is
enabled).

However, we see the error (void-function "get-process"). Likely, this is
just for DOS builds of Emacs.

Does the following patch fixes this?
