Precisely my point, Brian.  The usage and meaning of '...' are
almost impossible to find in the help system.  Could there be a
help page for it ?  Questions about '...' are reasonably frequently
asked on this list.

While we're at it, what could be done so that  help.search("logistic")
returns a reference to  glm()  and  help.search("regression") returns
references to both  lm()  and  glm() ?
