This is actually "V3" of the patch, but I forgot to add the -v3 when
sending from gerrit to the list.
The change is basically the same as in v1, just leaving the "real"
code alone, defusing it by setting c->c2.buf.len = 0 in the new
branch. Plus comments :-)
As in v1, this adds diagnostics to detect a non-fixable incompatibility
between 2.4.0-2.4.4 servers and DCO-enabled clients (it can only be fixed
by upgrading the server, not by a code change on the client side, or by
disabling DCO on the client - but neither can be done automatically).
Tested on the server testbed, which has DCO and no-DCO peers, V1 and V2,
which should trigger "false alarms" nicely.
Your patch has been applied to the master and release/2.6 branch (compat).
