[Orgmode] [BUG] read-char arguments: XEmacs incompatibility

[Richard KLINDA]

In org-clock.el there is a call to read-char with 3 arguments, but
XEmacs's version only takes 0 arguments, so it signals error (upon using
org-clock-in, for example).

|             (let (char-pressed)
|               (while (null char-pressed)
|                 (setq char-pressed
|                       (read-char (concat (funcall prompt-fn clock)
|                                          " [(kK)eep (sS)ubtract (C)ancel]? ")
|                                  nil 45)))
|               char-pressed))))
