(gnus-agent-mode): Use derived-mode-p. (gnus-agent-rename-group, gnus-agent-delete-group): Don't bind gnus-command-method and *-command-method to nil, but bind gnus-command-method to *-command-method instead! (gnus-agent-fetch-articles): Remove unused var `id'. (gnus-agent-fetch-headers): Remove unused arg `force'. (gnus-agent-braid-nov): Remove unused arg `group'. Adjust callers. (gnus-agent-save-alist, gnus-agent-save-local): Remove unused `item'. (gnus-agent-short-article, gnus-agent-long-article) (gnus-agent-low-score, gnus-agent-high-score): Move declaration before first use. (gnus-agent-fetch-group-1): Remove unused vars `arts', `category', `score-param'. (gnus-tmp-name, gnus-tmp-groups): Defvar them. (gnus-get-predicate): Push in front of the cache, rather than end. (gnus-agent-expire-current-dirs, gnus-agent-expire-stats): Defvar them. (gnus-agent-expire-group-1): Use push. Don't abuse dyn-binding. (gnus-agent-expire-unagentized-dirs): Don't rebind gnus-agent-expire-current-dirs since the defvar silences the warning. (gnus-agent-retrieve-headers): Remove unused var `cached-articles'. (gnus-agent-regenerate-group): Remove unused vars `point' and `dl'. (gnus-agent-regenerate): Simplify interactive spec and doc. * lisp/gnus/gnus-eform.el (gnus-edit-form-mode): Use define-derived-mode. * lisp/gnus/gnus-salt.el (gnus-tree-mode): Use define-derived-mode. Use save-current-buffer. (gnus-tree-mode-map): Initialize in the declaration. (gnus-pick-mouse-pick-region): Remove unused var `fun'. (scroll-in-place): Defvar it. (gnus-tmp-*): Defvar them. (gnus-get-tree-buffer): Use derived-mode-p. (gnus--let-eval): New macro. (gnus-tree-highlight-node): Use it to avoid dynamic binding of non-prefixed variables. (gnus-tree-open, gnus-tree-close): Remove unused arg `group'. * lisp/gnus/gnus-sum.el (gnus-summary-highlight): Remove `below' from the list of vars since it doesn't seem to be available. (gnus-set-global-variables, gnus-summary-read-group-1) (gnus-select-newsgroup, gnus-handle-ephemeral-exit) (gnus-summary-display-article, gnus-summary-select-article) (gnus-summary-next-article, gnus-offer-save-summaries) (gnus-summary-generic-mark): Use derived-mode-p. (gnus-summary-read-group-1, gnus-summary-exit) (gnus-summary-exit-no-update, gnus-kill-or-deaden-summary): Adjust calls to gnus-tree-close and gnus-tree-open.
