Broken simultaneous.itely?

[Carl D. Sorensen]

Graham,

In commit f83930a3e1a3fc9ad0198379275bd101b4fd29a4, for the file
simultaneous.itely, at about line 185, you changed

@code{<<@address@hidden address@hidden@}>>}

to

@code{<<{...} \\ {...}>>}

This change led make web on my machine to fail with the messages

Documentation/user/out-www//simultaneous.texi:310: Misplaced {.
Documentation/user/out-www//simultaneous.texi:310: Misplaced }.
Documentation/user/out-www//simultaneous.texi:310: Misplaced {.
Documentation/user/out-www//simultaneous.texi:310: Misplaced }.

When I replaced the @ symbols in simultaneous.itely, make web
completed successfully.

In addition, I found a place where "noteheads" instead of "note heads"
was used.

May I push the patch?  Or is there some better way to handle the {
characters inside the @code{} block?

Thanks,

Carl
