Cons less, be more careful about always using the environment, #'macroexpand
2011-12-30 Aidan Kehoe <kehoea@parhasard.net>
* eval.c (Fmacroexpand):
Don't cons if ENVIRONMENT is the same object as
byte-compile-macro-environment.
Always look up symbol- and other macros in the (possibly modified)
byte-compile-macro-environment, not the supplied ENVIRONMENT.
byte-compile-macro-environment reflects ENVIRONMENT, so that's OK
and preferred.
