downloadguix-64afc72962a486153f2198812bfb2822e8916aa8.tar.gz
status: Separate downloads upon '--verbosity=2'.
This is a followup to 1fa4aff1fbb46bbb9df8486ca12bfcfe6144458a,
reintroducing the newline previously emitted by 'guix substitute' upon
download completion.

With this change, with '--verbosity=2', each download occupies three
lines again, like so:

--8<---------------cut here---------------start------------->8---
downloading from https://ci.guix.gnu.org/nar/lzip/…-jsoncpp-1.9.2 ...
 jsoncpp-1.9.2  93KiB                4.2MiB/s 00:00 [##################] 100.0%

--8<---------------cut here---------------end--------------->8---

This makes the output more readable.

* guix/status.scm (print-build-event): When PRINT-URLS? is true, print
a blank line after the download.
