Thanks for the report, but even in the --help output,
I see this:

  Usage: tr [OPTION]... SET1 [SET2]
  ...
  -s uses SET1 if not
  translating nor deleting; else squeezing uses SET2 and occurs after
  translation or deletion.

I admit the wording could use some work (patch welcome!),
but it does get the idea across.

I'm using this
  ftp://alpha.gnu.org/gnu/fetish/coreutils-4.5.3.tar.gz
but that part of tr's --help hasn't changes for a long time.
