It's better style, and cheaper (often one assembler instruction
vs. a C funcall in the byte code), to use `eql' instead of `='
when it's clear what numerical type a given result will be. Change
much of our code to do this, with the help of a byte-compiler
change (not comitted) that looked for calls to #'length (which
always returns an integer) in its args.
