* help-fns.el (describe-variable): Describe ignored and risky local
variables in a similar way to that in which we describe safe ones.
* emacs-lisp/bytecomp.el (byte-compile-from-buffer)
(byte-compile-output-file-form, byte-compile-output-docform)
(byte-compile-file-form-defmumble, byte-compile-output-as-comment):
Give some more local variables with common names a "bytecomp-" prefix,
so as not to shadow things during compilation.
* emacs-lisp/cl-macs.el (load-time-value)
* emacs-lisp/cl.el (cl-compiling-file): Update for the name-change
`outbuffer' to `bytecomp-outbuffer'.
* emacs-lisp/elint.el (elint-standard-variables): Remove most members,
since the next two variables cover them automatically now.
(elint-builtin-variables, elint-autoloaded-variables): New.
(elint-unknown-builtin-args): Remove all members, since they can be
parsed automatically now.
(elint-extra-errors): New.
(elint-env-add-env, elint-env-add-macro): Use cadr.
(elint-current-buffer): Use or. Change final message.
(elint-get-top-forms): Use line-end-position.
(elint-init-env): Use cadr. Handle autoload, declare-function,
and defalias.
(elint-add-required-env): Doc fix. Use or. Standardize error.
(regexp-assoc): Remove unused function.
(elint-top-form): Set elint-current-pos, to record the start of the
top-level form, for compilation-mode.
(elint-form): Trap errors in macro expansion. Use dolist.
(elint-unbound-variable): Use elint-builtin-variables and
elint-autoloaded-variables.
(elint-get-args): Use cadr, or.
(elint-check-cond-form): Use dolist, cadr.
(elint-check-condition-case-form): Doc fix. Use cadr.
Use elint-extra-errors.
(elint-log): New function.
(elint-error, elint-warning): Use elint-log for a bytecomp-style format.
Distinguish errors and warnings.
(elint-log-message): Use with-current-buffer. Inhibit read-only.
Use a bytecomp-style format.
(elint-clear-log): Preserve default-directory. Inhibit read-only.
(elint-get-log-buffer): Use compilation mode. Disable undo.
Don't truncate lines.
(elint-initialize): Set builtin and autoloaded variable lists.
Only process elint-unknown-builtin-args if non-nil.
(elint-find-builtin-variables, elint-find-autoloaded-variables):
New functions.
(elint-find-builtin-args): Doc fix. Handle "BODY...)".
