X-Git-Tag: gnus-6_8-199811302358~66
X-Git-Url: http://git.chise.org/gitweb/?a=commitdiff_plain;h=5f33a88d14abc8a2dc742fbf84de8725bd4ce365;p=elisp%2Fgnus.git-

	* lisp/nnheaderxm.el (nnheader-xmas-Y-or-n-p): New function.
	It will be used for the substitute of `nnheader-Y-or-n-p' under
	XEmacs.

	later except for XEmacs.
