pdb gives contradictory messages when I try to leave it:

"exit" gives me the message 'Use Ctrl-D (i.e. EOF) to
exit.'; when I then press "Ctrl-D", nothing happens.
Only "quit" will exit the debugger:

freefly:1> python2.2 /usr/lib/python2.2/pdb.py
/tmp/xxx.py
> <string>(0)?()
(Pdb) exit
'Use Ctrl-D (i.e. EOF) to exit.'
(Pdb) Ctrl-D quit
freefly:2>

The cause for this trouble is that exit() is defined in
site.py to issue that warning, but then, "Ctrl-D" is
not accordingly handled in pdb.py. So either pdb.py
should be fixed to handle "Ctrl-D" like "quit", or
"exit" should be changed in pdb.py to either quit the
program or just do nothing.

The easiest solution was to add exit as an alias of quit,
and that's what I've done in CVS. There's still the problem
with ^D being ignored; I'd be happy to get a patch for that.
