For defuns to be in an empty environment and lambdas to take lexical args.

save-window-excursion, condition-case, and track-mouse.
Fix defconst/defvar handling.
(byte-compile-unwind-protect, byte-compile-track-mouse)
(byte-compile-condition-case, byte-compile-save-window-excursion):
Provide a :fun-body alternative, so that info can be propagated from the

Skip directories. Find files literally, with only safe local vars.
* etc/NEWS: Mention copyright-fix-years and ranges.
* lisp/emacs-lisp/copyright.el (copyright-find-copyright)
(copyright-update, copyright-fix-years):
Do the initial widen and move in copyright-find-copyright.
* lisp/emacs-lisp/copyright.el (copyright-find-copyright): New function,
split out from copyright-update-year.

copyright. Update license regexp, and remove no longer needed
Esperanto stuff.
