Port #'window-buffer-height, #'fit-window-to-buffer, & window, buf, functions. lisp/ChangeLog addition: 2008-08-31 Aidan Kehoe <kehoea@parhasard.net> * window.el (only-window-p): New. Check if WINDOW is the only window in some context, normally its frame. (one-window-p): Implemented this in terms of #'only-window-p, calling it on the selected window. (window-buffer-height): Uncomment this, make it work. (count-screen-lines): Support a BUFFER argument. (fit-window-to-buffer): Uncomment this, correct its implementation to work with XEmacs. * help.el (temp-buffer-resize-mode): New. Name taken from GNU, implementation our own. * (resize-temp-buffer-window): New. GNU-compatible alias for #'shrink-window-if-larger-than-buffer. * dumped-lisp.el (preloaded-file-list): Move easy-mmode before help, now that the latter uses #'define-minor-mode. * frame.el: Point to #'temp-buffer-resize-mode in a comment. Some of this code is from GNU; help.el CVS version 1.327 of 2007-03-21, window.el CVS version 1.122, of 2007-06-24. Both these are GPLV2 or later.
