Cause MetaPost graph package to ignore '#'-comments

This file modifies the Grdln_ routine of the MetaPost graph package, so that it can parse and ignore comment lines in data files starting with a ‘#’ sign, similar to the conventions in Gnuplot.

Note that the graph package will still interpret an empty line as “end of data” (even if it precedes any data).
