... as in APPEND1 and NCONC1. These come from unimaginative programmers who
wanted a name similar to APPEND and NCONC, that's all. There was no intention
of having it mean "APPEND one element..." or anything sensible. It's a style
going back to assembly programming, where you had an "entry point" such as
SQRT, and you needed auxilary, internal labels: SQRT1, SQRT2, etc. The "best"
example I can remember from LISP.MAC is FIX which begat FIX1 which begat FIX1A,
which is the most useful of the three.
