This patch from Rik Faith <faith@alephnull.com> fixes a potentially
non-NULL terminated string problem that could result from the use
of open_memstream(). Manuel may have a better solution, but this
one works for me, since with this plus the popen fix I can now run
things like gdb properly. Thanks Rik!
