I'm sorry but "reuse" is a fairly important concept in a project like
this.  The proc functions, in particular, have been prone to NIH and I
don't want to see even more there if we can possibly help it.

So, I'll reiterate my suggestion that you look at, e.g.,
mount_item::fnmunge and possibly think about generalizing it if it isn't
quite up to the task.

I'll also go on record as advocating that this not be part of a bugfix
release.  It seems too much like a last minute change to me.

Getting it into cvs main, however, seems like a good idea.
