Subject: [PATCH] Extend Ruby word characters to include valid identifier chars
 (#7824)

In Ruby `_$=@!:?` can all be part of an identifier. If we don't have
them in this list, autocomplete doesn't work as expected.

See: https://gist.github.com/misfo/1072693

This fixes one part of #7819 but not the whole ticket.

Release Notes:

- Fixed completions in Ruby not working for identifiers that start or
end with special characters (e.g.: `@`)
