0.pre7.92:
made function names (as returned by FUNCTION-LAMBDA-EXPRESSION
and used by BACKTRACE) for DEFUNed functions mostly
reasonable again, e.g. PRINT instead of
"top level locall PRINT"
...made SETFable %FUN-NAME to encapsulate this
...renamed FUNCTION-DOC to %FUN-DOC for consistency
...got rid of NAMED-LAMBDA, since cold-load issues make it
awkward to use it in DEFUN where I intended to use it,
and there's no urgent other place to use it
...made %DEFUN use SETF %FUN-NAME
(There are still function-name infelicities left, especially
for closures where there's no good implementation of
SETFable FUN-NAME until weak hash tables work, but at
least most BACKTRACE entries look better now.)
