The case was about non numbered power symbols, a special case.  I'd prefer if inheritance was overridable,
so I could rename Vdd to names such as 20V, 16V, 24V, 1.7V, 3.3V, 20V_IN, etc -- all with one library symbol for +/-
and one for ground.

That might still be needed.  Will check soon.

experimental sounds closer to an intuitive style.  Thanks for writing all the python versions of gschem internals.

There was a double T1 naming even if the slots mention was useless, and I corrected it, and the error list got shorter.
geda-gaf master didn't show those drc errors, probably since it reported lots of U? problems with
my modified power symbols and made no output.net drc2 listing, only messages to stdout.

I apologize for not posting the whole error message file, but I had already worked past it as I'm working
on a OSHW project with git, so I tidied that up before committing more work to the repo.

output.net drc2 listing was there.

output.net drc2 listing + some way to mention symbols by name that have problems.

I'll not be able to switch back to using geda-gaf master until back from a big trip in March/April
because of deadline pressure.  (unless geda-gaf 1.9 branch is broken really badly in a way I have not hit yet)
So others please test the recent changes -- I won't be testing.
