Hi Pedro,

VMware has a remote target for which "info threads" stopped
working after you added your remote multi-process patch in
September.  I've finally got around to figuring out why.

The docs don't actually say whether this message should have
leading zeros, but it always used to (you can check out the
old sprintf spec).

If there's no compelling reason for removing them,
do you mind if we put them back?   ;-)
