This does not, however, appear to answer his question as I parse it - in paraphrase, "why does the --help output not provide this kind of information?".
Because the effect is not limited to rm, so "caveat regarding shell limitations" or something less wordy could arguably be added to the 35-ish coreutils which take a list of files.
Ditto for "files which begin with a dash", "dotfiles not matched by *", and any other getopt or shell issue which applies to any app which understands lists of files in argv[].
The answer as I understand it would be something along the lines of "because find is orthogonal to rm and the output of a given program's --help should be concerned only with that program", and indeed there may be no better answer available.
I agree with this viewpoint. (Remember that the original poster's error message was printed by bash, not rm.)
