Well, if the system is Unixoid enough to *have* a stat() system call, and you
stat() a file on a file system that doesn't support multiple hard links, it
will just set the stat.st_nlink field to 1.  And I'm going to make a guess that
most nmh users are using a sane filesystem that does have multiple links.

The bigger thing will be bulletproofing it for things like the purported file
actually being a directory or a symlink or other non-file entity.
