mtree(1) recent POLA violation

  Hi,

the recent mtree(1) import from NetBSD brought one change, that is a POLA
violation and I would also question if the new behavior is desired.

Before the import 'mtree -c -R all' would leave 'type=' keywords, despite '-R
all' asks for removing all keywords.  The 'type=' is special, since this
keyword is required to reconstruct a new spec.

In other words before the import this was working:

mtree -c -R all | mtree -C

Now this is broken.  The above was standard idiom to compare installed to tree
to a specification.  Now the correct syntax to get the same behavior is this:

mtree -c -k type | mtree -C

I'll let other to decide do we want to fix this POLA violation or not. At least
this needs to be recorded in Release notes.
