Wrong advertised-calling-convention

  From subr.el: looking-back declares optional argument LIMIT mandatory.

Such calling-convention deserves a place in doku, but should not send
wrong info out of didactics
Are you saying that using advertised-calling-convention is wrong
everywhere,

In the way it's implemented, seems a bad idea everywhere.
It cheats the user delivering wrong resp. incomplete signatures.

If certain usages are discouraged, that might be told in docstring, by re-writing the function etc.

  or just in this one case?  If the latter, what is special
about this function?

Thanks.
