[erlang-patches] better delete_any in gb_{sets, trees}, better difference in gb_sets

[Henrik Nord]

Hi
Your branch  "gb-delete_any" has been reviewed with the following comments:


fma/gb-delete_any
  The commits should have been squashed.

  Rejected. Breaks the documentation which says that it does nothing
            if the key is not present.


And for you branch "gb_difference" the comments are as follows

fma/gb_difference
  The commits should have been squashed.

  Clarify: Explain what is not sane with the current
           gb_sets:difference/2 and gb_sets:is_subset/2.


Thank you for your contribution!
