GnuCash OFX import not matching accounts of same ID

Thanks for the input. Good to know that multiple-account activity is well
supported by OFX.
However, the main issue is that I thought OFX account IDs were matched to
GnuCash accounts.
They are not!

While this would be theoretically possible, I would rather not fork the OFX
standard.
Right now I am considering how QIF could fill in the gap here. Let's see
how that goes. :)
