Publishing multiple packages should not say “You may press ctrl-c to skip waiting”

[kpreid]

Problem

When using the new unstable support for publishing multiple packages in one command, Cargo prints its usual message during uploading:

You may press ctrl-c to skip waiting; the crate should be available shortly.

However, this does not make sense for any packages but the last one, because the only things it could possibly do are cancel the remaining packages (unwanted), run the risk of erroring out due to not waiting before publishing the next package (unwanted), or do nothing (misleading).

Possible Solution(s)

Cargo should not print this message. Perhaps a more useful while-you-wait message would be to report how many packages remain to be published (or how many have been and the total).

The first question is if the message is serving its purpose.

If so, then it would be needed in these cases. What could instead work is to re-word it to tell users that the current package would be available shortly but that there are X packages that are unpublished.

The message was added in #11230 (though started in #11062) and tweaked in #11713. Neither seems to talk about the motivation. #11062 initially didn't call out ctrl-c but I'm not seeing the discussion where it changed. I also checked meeting notes from that time and I'm not seeing it.
