Don't augment ENVIRONMENT when that's not indicated, #'macroexpand. This reflects better understanding on my part of the &environment macro keyword, and I've expanded the Lisp manual and docstrings to reflect that. lisp/ChangeLog addition: 2012-05-06 Aidan Kehoe <kehoea@parhasard.net> * cl-macs.el (block): Comment on why we can't use &environment here. * cl-macs.el (defmacro*): Document &environment in more detail. * cl-macs.el (macrolet): Use &environment, instead of referencing byte-compile-macro-environment directly. * cl-macs.el (symbol-macrolet): Ditto. * cl-macs.el (lexical-let): Ditto. * cl-macs.el (labels): Ditto. man/ChangeLog addition: 2012-05-06 Aidan Kehoe <kehoea@parhasard.net> * lispref/macros.texi (Expansion): Cross-reference to documentation of #'cl-prettyexpand, #'defmacro* when talking about #'macroexpand. tests/ChangeLog addition: 2012-05-06 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el: Use &environment appropriately in #'macrolet, instead of relying on #'macroexpand to guess what we mean.
