Thanks. I'll leave the [5] restriction call to someone else, seems it
does no harm to me though (not as if we'd change it that often anyway).
Revised patch below. I looked through other places that might be affected,
but did not see anything else except ecpg/preproc/preproc.y, which
looks as though it's already been changed to handle four events.
