This would make the output in Emacs PO mode (where the file name is
usually a long pathname) harder to understand.

Also, msgfmt is often used manually by a translator, and the translator
is mostly interested in the 3 numbers; everything else dilutes her
attention.

I agree that it would be welcome to have this in po/Makefile.in.in,
however we have a problem here since we cannot use "echo -n" portably.

This is inherent in the use of make's "-j" option. When you use
"make -j" you could as well pipe stdout and stderr to /dev/null, because
the only reproducible effects of "make -j" are 1. the side effects on
disk, 2. the exit status of the command. You can simply not expect to
understand "make -j" output.
