Subject: 	* texinfo.tex (\dosubind): Don't do \vskip to preserve \lastskip
X-Git-Tag: 3.77~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=65a7296e2c81b04761b3f024572310a02c9de691;p=platform%2Fupstream%2Fmake.git

	* texinfo.tex (\dosubind): Don't do \vskip to preserve \lastskip
 		unless we are in vertical mode.  Otherwise we might end a
 		paragraph prematurely, and \folio won't get expanded by
 		\output.
 	Report from: "Richard E. Stone" <res@rstone.mn.org>
