OK.

Well, partialy. At least, the command being executed is logged, its stdout,
as well as its stderr. So, if the commands prints some progress status (as
'cp -v' was used for), or prints errors (on stderr), it should be logged
appropriately. And because the command being executed is logged, it's always
possible to hand-type it for further investigation.

The 'cp -v' was really intended for cases where the copy could take a bunch
of time, see eg. this changeset:
    http://crosstool-ng.org/hg/crosstool-ng/rev/c3ff88a0c788

So, removing the '-v' from 'cp' incantations would just look like no progress
for a little while for unsuspecting users. That should be eventually worked
around with a _usability_ fix, but for now, it's time for a _feature_ fix.

And yes, I know, there are a bunch of pending patches on the list. I'll
catter to them during the week, and then hope for the release to be ready
before the end of the month (and obviously, before FOSDEM! Beer, yeah! :-))

Yann E. MORIN.
