Normally return a compiled function if one argument, #'constantly. 2010-02-24 Aidan Kehoe <kehoea@parhasard.net> * cl-extra.el (constantly): Normally return a compiled function from #'constantly if we are handed a single argument. Shouldn't actually matter, the overhead for returning a single constant in a lambda form vs. in a compiled function is minuscule, but using compiled functions as much as possible is good style in XEmacs, our interpreter is not stellar (nor indeed should it need to be).
