Updating Homebrew...
Warning: vim: --override-system-vi was deprecated; using --with-override-system-vi instead!

Same on Siera:

Warning: vim: --override-system-vi was deprecated; using --with-override-system-vi instead!

@rickypai I read that message as a whole, meaning that, no, you don't want to create those symlinks for the same reason homebrew doesn't. The last part of the message is therefore telling you that you can have them resolve first for you interactively by instead putting them first in your PATH.

When I ran "brew tap homebrew/versions" I got this message:
Error: homebrew/versions was deprecated. This tap is now empty as all its formulae were migrated.

Looks like --with-default-names is now deprecated https://stackoverflow.com/a/34815955
