bindings feature request

Hi,
 I would love it if the python bindings would act similarly to the
command line for erasures.

ie:

if I have foo.i386 and foo.x86_64 installed I can run rpm -e foo.i386
and it will remove _just_ the i386 arch of foo
if I do the equivalent in python:
ts.addErase('foo.i386')

it will remove all things named 'foo' in the rpmdb.

which seems very very dangerous :)

it'd be really grand if addErase() had a way to take a header like
addInstall does.

thanks
