[racket] Should `raco pkg update <x>` presume --update-deps?

Exactly.

My info.rkt deps is using the original '(pkg ver) form because
#:version came later.  At some point after 6 I'll cut support for
5.3.5 and 5.3.6, but for now I'm still supporting and making Travis
test against them.

Other than please not breaking any such deprecated package stuff, at
least not quite yet, there's probably nothing actionable on your end
for this. (Except maybe to release 6 :).)

But if you do need more details the user posted here:

Thanks.
