@* in @macro gives error when using texi2pdf

[Christopher Dimech]

Introducing @* in @macro gives error when using texi2pdf.
But using @* works when output to html.

@macro Begof{entity, label, title}

@ifclear NoLabel
   @* @noindent @strong{\entity\ \label\.} @ @emph{\title\}
@end ifclear

@ifset NoLabel
   @* @noindent @strong{\entity\.} @ @emph{\title\}
@end ifset

@end macro

@Begof{Definition, 3.2, Analysis of Signals}
