pdb name truncation

I've had problems with this, too, and your post induced me to finally
fix it instead of work around it. :) (though usually you can get the
complete error by re-executing the line that caused the error from the
pdb prompt, even that's a bit of a pain.)

Stick this in a file my_pdb.py in a directory that'll be in your
sys.path, and do

"from my_pdb import set_trace"

or whatever it is you usually use from there.

If people care, I could submit a patch to fix pdb directly.  It'd be a
lot simpler to do this sort of thing if each instance of pdb.Pdb created
its own Repr.repr instance.
