coreutils bootstrap cvs -z3

[Karl Berry]

The bootstrap script in coreutils hardwires -z3 in the cvs call:

cvs -z3 -q -d ${CVS_PREFIX}cvs.savannah.gnu.org:/cvsroot/gnulib co gnulib ||

Could you leave that up to the installer?  On one of my servers, due to
firewalls (I guess), compressed cvs traffic does not work reliably.  I
doubt I'm the only one stuck with that problem.

(Yes, it's obviously trivial to modify the script, but ...)

Thanks,
