Please do not quote just a raw object name, but annotate it so that
we can more easily tell what the change was about and how far back
in the history it was done without having to run "git show -s" on
it.

Let me double check if I understand Brian and the above correctly:

 * The original 2386d658 (Add first cut at "git protocol" connect
   logic., 2005-07-13) did not even care that the IPv6 syntax was
   valid or not, and worse yet, it did not correctly handle literal
   addresses in brackets;

 * Later we started supporting literal addresses in brackets, but
   "user@[literal]:port" form did not work.  Instead, a bug in the
   parser allowed "[user@literal]:port" (which is not a valid way to
   spell such things) to work as if it were "user@[literal]:port",
   which is what users would expect.

 * This three-patch series is an attempt to allow that kosher
   syntax, "user@[literal]:port", to work.

 * It does not terribly matter if we broke the invalid syntax
   "user@literal:port" without brackets, and it might even be
   beneficial if we declared such addresses invalid and deprecated
   for the sake of uniformity with other protocols.  Making that
   judgement, however, is outside the scope of this series.
   "user@literal:port" will continue to behave as it did before.

Is that what is going on?

If that is the case, I think it addresses Brian's concern well.

Thanks.

(I haven't checked the patch text itself yet, though).
