What to do when un-nominating bugs for 1.2

[Dan Kegel]

In the gcc world, when a bug is targeted for release X
and doesn't make it in time, it is retargeted for release X+1.

So when 1.0 rolled around, I retargeted the leftover 1.0-targeted
bugs at 1.2.

Can we do the same this time, and retarget 1.2 bugs for 1.4
if they're not going to be fixed for 1.2?

The only time one should simply remove the 1.2 target
is if we decide the bug really isn't even a candidate for 1.4
(or was nominated for 1.2 in error).
