Without going into all the messy details, a V3 program is going to

less than 2112 bits, etc.

Proposed text to fix this is to add to the end of the paragraph:

  Note that when assembling a backwards compatible message, there may
  be other issues that be resolved in addition to using the IDEA
  cipher.

I'd also be fine with dropping the paragraph altogether if there is
not much interest in supporting PGP 2.

Or, it should be said - I'm also fine with doing nothing.  2440bis is
not a programming guide, and this is hardly a world-shatteringly
important issue.
