+\subsection{\pkg{bm}: Better support for commands with optional arguments}
+Some uses of optional arguments that were supported by \cs{bm} stopped
+being supported (in 2004) when \cs{kernel at ifnextchar} was used
+internally by the format instead of \cs{@ifnextchar} This update
+handles both versions of this command and restores the original
+behaviour.
