Subject: [PATCH] * liece-url.el: Don't require browse-url when compiling.
 (liece-url-browser-name): Abolish.
 (liece-url-prepare-browser-function): Abolish.
 (liece-url-mail-regexp): Abolish.
 (liece-url-browser-function): Abolish.
 (liece-url-link-action): Use browse-url directly.
 (liece-command-browse-url): Ditto. (liece-url-add-buttons):
 Remove local variable `url-start', `url-end' and `url'.
 Suggested by: Kenichi OKADA <okada@opaopa.org>
