#15 Postscript output sometimes incomplete

[Lynn Kerby]

I'm not sure why this is happening, but I keep creating
documents that are missing the final showpage when
printed as postscript to file. I've looked at the code and
it appears to always close the stream properly, but I'm
still getting files that don't print because they are
truncated.

I added a call to fflush() after outputing the final
showpage
in sp_module_print_plain_finish() and that seems to always
work.

Patch to add fflush() on ps output stream before closing descriptor

Thank you. I added this, and moved fclose to ::finish as well.
