Download progress interleaved with compile output

[Mark H Weaver <mhw@netris.org>]

I recently installed a large number of packages in a single "guix
package -i" command, and in the resulting transcript I see download
progress reports interleaved with compile output, e.g.:

--8<---------------cut here---------------start------------->8---
gcc -DHAVE_CONFIG_H -I. -I../include  -I ../src -I ../include -I ../tools  -Wall -W   -I/nix/store/zs7rsahwk9hmfypgazw1fkk2kg6rymvp-libogg-1.3.0/include   -g -O2 -MT katalyzer-kutil.o -MD -MP -MF .deps/katalyzer-kutil.Tpo -c -o katalyzer-kutil.o `test -f 'kutil.c' || echo './'`kutil.c
http://mirror.yongbok.net/.../guile-ncurses-1.3.tar.gz	 18.0% of 712.2 KiBmv -f .deps/katalyzer-kutil.Tpo .deps/katalyzer-kutil.Po
gcc -DHAVE_CONFIG_H -I. -I../include  -I ../src -I ../include -I ../tools  -Wall -W   -I/nix/store/zs7rsahwk9hmfypgazw1fkk2kg6rymvp-libogg-1.3.0/include   -g -O2 -MT katalyzer-kstream.o -MD -MP -MF .deps/katalyzer-kstream.Tpo -c -o katalyzer-kstream.o `test -f 'kstream.c' || echo './'`kstream.c
mv -f .deps/katalyzer-kstream.Tpo .deps/katalyzer-kstream.Po
--8<---------------cut here---------------end--------------->8---

Is this intentional?
