This matches what I implemented for at least one vector machine.
And my intuition agrees with yours -- info registers should produce
a display that fits in one screen, if possible. Masses of registers
should be displayed some other way.

Not having seen your patch (?), I wonder how you distinguished
vector registers from generic ones.
