Subject: No error when marking functions whose body just returns a constant.  Handle
X-Git-Tag: ttn-vms-21-2-B4~10735
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=7119cefec2c8037cf5d8797932c106f19b235304;p=emacs.git

No error when marking functions whose body just returns a constant.  Handle
screwy top-level macros that create functions and store them as properties of
symbols.  Support for CL's function* macro.
