Cmd-E (Edit -> Use Selection for Find") in most macOS apps follow the
convention that it shares to the system Find Pasteboard, while Cmd-G
uses the Find Pasteboard to find the next item. Make Cmd-E always do
that even if MMShareFindPboard is set to NO. This way, normal searches
in Vim wouldn't pollute the system find pasteboard, but could still have
a way to share to it by using this action.
