+ * woman.el (woman-mode-map): Copy button-buffer-map instead of
+ making a new keymap. Don't bind mouse-2. Bind M-mouse-2 to
+ `woman-follow-word' instead of `woman-mouse-2'.
+ (woman-follow-word): Renamed from `woman-mouse-2'.
+ Follow current unconditionally, since this function is now only
+ bound to M-mouse-2. Use accessor functions.
+ (WoMan-highlight-references): Use `make-text-button'.
+ (woman-xref): New button type.
+
* loadup.el ("faces"): Move load before loading "loaddefs.el".
("button"): New load, just before "help" (which uses it).
Should include ?e, ?o (page even/odd) and either ?n (nroff) or ?t (troff).
Default is '(?n ?e ?o). Set via `woman-emulation'.")
