It makes a lot of sense to use COMPILE-FILE-PATHNAME now that it does what we
want. Applied as [2][] in github.com pull [355][].  Thanks for the code.

Agreed to ignore the PATHNAME-VERSION complications, until someone argues for
restoring them.  I can’t think of any current filesystems that the Bear
encounters where a version would have an unambiguous meaning which would be
portable to the ones I commonly use.
