Changing output files for scs2pdf

I was thinking about what Scott suggested concerning using syslog(3) for
the error messages when I thought it might be a good idea to change where
scs2pdf writes it's output.  So I made it so that if the environment
variable TN5250_PDF is set scs2pdf would open the filename specified
there, otherwise it opens stdout.  But after doing so I realized that by
smart use of the outputfile argument to lp5250d pretty much anything could
be done without needing an environment variable.  So I'm wondering if
anyone can think of a use for being to set the name of the generated PDF
via a method other than the outputcommand argument.  Its only about 10
lines of code, but this ain't MicroSoft and we don't features for the sake
of having features.

I'm still thinking about syslog.  It is probably the best way to, any
enterprise-level (buzzword!) program ought to tell people what it is doing
if they need it.  Maybe with priority LOG_DEBUG?

Anyway, if people think its useful, the diff is at:
