I believe I implemented this (if it wasn't already the case in the
previous code) as a protection against malformed references, to stop too
much of the file being interpreted as a cross reference in case it wasn't
one.  It's extremely unlikely a node name is long enough to cross over
three lines.

One example of where this might happen is if with input like

@strong{Note that bread should not be kept in the fridge.}

@xref{node,,,manual, The Manual}.

The output is

   *Note that bread should not be kept in the fridge.*

   *Note (manual)node::.


The info reader successfully avoids seeing the first line as a cross
reference.  It's not perfect though:

   *Note that bread should not be kept in the fridge: it goes off too
soon.*

does get interpreted as a cross-reference because of the colon.
