ftruncate() seems to work right for FreeBSD NFS, and there is code to
support it in our support disk file systems (ufs, msdosfs, ext2fs).

I noticed that it also "succeeds" for /dev/tty.  It "succeeds" and has no
effect for all special files.  OTOH, lseek() returns ESPIPE unless the
file type is DTYPE_VNODE.
