Leiningen 2.9.0 & whidbey 2.1.0 adding newline to output?

[drbobbeaty]

I just updated to Leiningen 2.9.0 and tried whidbey 2.1.0 and the result was that extra newlines are being added to the output:

If I go back to Leiningen 2.8.3 the extra newlines aren't there. Same whidbey version.

Is there something about whidbey that can be configured for the change in nREPL?

This is an unfortunate side-effect of the new approach to print IO in nrepl. Previously, whidbey would use puget to fully render the result as a string (without a newline) and then send it to the client. Now, output is streamed to the repl client, and this doesn't give whidbey an opportunity to trim the trailing newline. See #28 for some more context.

In the future this could be fixed in a couple of ways, but for now there's no easy workaround.

Thank you so much for a good description of the issue. I really appreciate it.
