For those who came in late, this started on gnu-emacs-sources looking
to get makeinfo-buffer use Info-mode to show its foo.info output, as
opposed to the current raw buffer (which in particular is not good
when using the default file splitting, since foo.info is merely a tags
table in that case.)

	* textmodes/makeinfo.el (makeinfo-buffer): Display result using
	Info-mode.
	(makeinfo-compilation-sentinel-buffer, makeinfo-current-node):
	New functions.
	(makeinfo-compile): Add a sentinel parameter.
	(makeinfo-compilation-sentinel-region): Renamed from
	makeinfo-compilation-sentinel, and makeinfo-temp-file now never nil.
	(makeinfo-region): Use this.
	* info.el (Info-revert-find-node): New function.

Reindenting has bloated the makeinfo-compilation-sentinel-region diff,
the only change, as stated, is no need to check for makeinfo-temp-file
being nil.
