[Rd] RFC: What should ?foo do?

[Deepayan Sarkar]

For what it's worth, I use ?foo mostly to look up usage of functions
that I know I want to use, and find it perfect for that (one benefit
over help() is that completion works for ?). The only thing I miss is
the ability to do the equivalent of help("foo", package = "bar");
?bar::foo gives the help page for "::". Perhaps that would be
something to consider for addition.
