Check types (unless `byte-compile-delete-errors' is t), #'char<, #'char=, etc.
src/ChangeLog addition:
2011-04-23 Aidan Kehoe <kehoea@parhasard.net>
* editfns.c:
* editfns.c (syms_of_editfns):
Implement #'char= in cl-extra.el, not here, accepting more than
two arguments as Common Lisp specifies.
lisp/ChangeLog addition:
2011-04-23 Aidan Kehoe <kehoea@parhasard.net>
* cl-extra.el (define-char-comparisons):
Add type-checking when the various character-specific comparison
predicates are used; don't check types if
byte-compile-delete-errors is non-nil at compile-time, instead use
the corresponding built-in numeric byte codes.

Each one is a vector of three elements: @itemize @minus @item The first element is the text of the button. @item The second element is the @dfn{callback}. @item The third element is @code{t} or @code{nil}, whether this button is selectable. @end itemize @end itemize If the callback of a button is a symbol, then it must name a command. It will be invoked with @code{call-interactively}. If it is a list, then it is evaluated with @code{eval}. One (and only one) of the buttons may be @code{nil}. This marker means that all following buttons should be flushright instead of flushleft. The syntax, more precisely: @example form := <something to pass to `eval'> command := <a symbol or string, to pass to `call-interactively'> callback := command | form active-p := <t, nil, or a form to evaluate to decide whether this button should be selectable> name := <string> partition := 'nil' button := '[' name callback active-p ']' dialog := '(' name [ button ]+ [ partition [ button ]+ ] ')' @end example @node Dialog Box Functions @section Dialog Box Functions @defun popup-dialog-box dbox-desc This function pops up a dialog box. @var{dbox-desc} describes how the dialog box will appear (@pxref{Dialog Box Format}). @end defun @xref{Yes-or-No Queries}, for functions to ask a yes/no question using a dialog box.
