@itemize in @macro fails

[Stephen Gildea]

The following input file fails with texinfo.tex 1999-09-25.10.
I get this error

! Extra }, or forgotten @endgroup.
@starti ...i}@scanmacro {@itemize @bullet}@egroup 

It works fine with makeinfo.


\input texinfo
@setfilename start-end

@macro starti
@itemize @bullet
@end macro
@macro endi
@end itemize
@end macro

@starti
@item an item
@item another
@endi

@bye
