patch for metapost.trm

[Allin C. <cot...@wf...>]

I just noticed that if a gnuplot file contains a detailed 
specification of an area to be filled with the filledcurve style, 
the metapost terminal writes out a very long "fill" line, which 
can exceed the length that mpost will process.

The attached patchette arranges for such a fill line to be broken, 
in the same way that a long "draw" line is broken.
