Rather than fixing RFC-1991 support, why not go in the other direction and make it clear that it isn't supported, and won't work?  I did a bunch of work to make --pgp2 work well and interoperate with PGP 2.x over a decade ago.  Even then it was intended as a stopgap measure until people finally stopped using PGP 2.x.  Over 10 years later, it's well past time to kill it.
