See the comment for the bug and the fix. This one probably wants to
go back to Berkeley.

+ /* Modified 10 December 1989 by Jon Rochlis, MIT Network Services.
+ This code declared two char arrays L[32], R[32] and expected them
+ to be contiguous (i.e. the code references L[33] and expects to get R[0].
+ This lost on the MAC under MPW 3.0 ... Changing it to be L[64] and
+ R = &L[32] seems to have done the trick.
