Re: plpython does not honour max-rows

plpy.execute is a thin wrapper around SPI_execute, which does document
this point:

   If <parameter>count</parameter> is zero then the command is executed
   for all rows that it applies to.  If <parameter>count</parameter>
   is greater than zero, then no more than <parameter>count</parameter> rows
   will be retrieved; execution stops when the count is reached, much like
   adding a <literal>LIMIT</literal> clause to the query.

Since that's stood for a few decades now, changing it seems impossible
from the backwards-compatibility standpoint.  However, it does seem
appropriate to repeat that material in the wrapper's documentation.

I wonder whether the similar plperl and pltcl wrappers are also
documentation-shy here.
