Ok, makes sense.

Where's the patch for that, I hadn't noticed it being posted yet ?

If 'make' was running with V=1, then also letting docker download be
verbose makes sense.

The plain 'make' though is intentionally quite terse, just giving a
list of files meson compiles. Right now, the output ends up looking
like this:

which I feel is quite unplesant, especially when you then get
multiple parallel docker downloads concurrently refreshing the
screen and overwriting each others' output.

With regards,
Daniel
