+	* latex2e.texi (Math symbols): \bigtriangle{up,down} are binary
+	operators (mathbin), not [big] operators (mathop), per fontdef.dtx.
+	And \varbigtriangle{up,down} are synonyms.
+	Report from Masato Shinokawa, 18 Apr 2022 10:36:24.

 	* latex2e.texi (\lastlinefit): reset to 0 (latest texinfo.tex sets
 	to 500) to avoid numerous new underfull box warnings for last
 	lines of paragraphs.
