`t', as per definition. I'm not too happy with that; because there is
also the case of CDs or USB sticks, where the access might be slow,
though these devices are not mounted in the sense of file-mounted-p.

I would prefer a function which returns "fast" or "slow". Since we
cannot know it without testing (what shall be avoided), we have only
such "second hand indications".

One could consider additional regexps, which tell "when the mount
point matches this regexp, return `t' for file-mounted-p", and the
contrary case with the other regexp. But this would make the handling
more complex.
