Note that I said GPL or equivalent.  Specifically these sections make 
it GPL equivalent:

   c) Provide all the changes, including source code, with every copy of
           the modified Vim you distribute.  This may be done in the 
form of a
           context diff.  You can choose what license to use for new 
code you
           add.  The changes and their license must not restrict others 
from
           making their own changes to the official version of Vim.

        e) When the GNU General Public License (GPL) applies to the 
changes,
           you can distribute the modified Vim under the GNU GPL version 
2 or
           any later version.

It's not identical to the GPL license, but the Apache license isn't 
identical to MIT either and I grouped them together.
