standalone @itemx

[Tom Tromey]

The manual says:

      Use address@hidden' for the first entry, and address@hidden' for all 
subsequent
    entries; address@hidden' must always follow an address@hidden' command, 
with no blank
    line intervening.

But in the GDB manual we had a @table that had an entry like so:

    @item =thread-group-started,id="@var{id}",pid="@var{pid}"
    A thread group became associated with a running program,
    either because the program was just started or the thread group
    was attached to a program.  The @var{id} field contains the
    @value{GDBN} identifier of the thread group.  The @var{pid} field
    contains process identifier, specific to the operating system.

    @itemx =thread-group-exited,id="@var{id}"[,exit-code="@var{code}"]

I think makeinfo should give an error on this.
