The latter.  The OS (or more precisely: the command line shell) should
know what to do with 2>.

I'm not aware of any docs other than what Petr may have put into the
README of the binary package.

Actually, the major use case is to have a gnuplot on Windows that supports
piping from within, as in back-tick expansion, data file filtering and
output to pipes:

	set title `my_title_generator`
	set out "| lpr -P myprinter"
	plot '< awk -f myscript datafile'

The fact that it causes wgnuplot to display a console is a side-effect
of the actual modification.

In the end, I suspect we'ld have to rewrite large parts of, possibly the
entire MS Windows text output routines in gnuplot (i.e. src/win/wtext.c).
I once started down that road, but never made it very far, and didn't 
publish the results.
