BUG?: gpg 1.4.9 uses incorrect OpenPGP key type when creating subkeys via --edit-key

[Adam M.]

When creating RSA Encrypt-Only (type 2) or RSA Sign-Only (type 3) 
subkeys using the --edit-key "addkey" command, gpg 1.4.9 seems to create 
the subkey as type 1 (RSA [Encrypt or Sign]).

Either that, or --list-keys --with-colons reports the type as 1 even 
when it's actually 2 or 3.

Since GPG forces the user to choose RSA Encrypt-Only or RSA Sign-Only, 
you'd expect it to actually use that in the created subkey.

Is there some reason for this? Backwards compatibility maybe? Or is it 
just a bug?
