Forage X for <not> Y

[whitt]

Suggestion is for a modification to the forage command to allow it to take not as well as for as an optional argument.

For example,
forage rocks for not quarried
To avoid leaving multiple instances of quarried whatever-stone about when you'd be happy with anything smaller.

or
forage food for not grub
because you'd never pick one of those gross things up.
