should enscript set an exit code?

I have a fresh install of 16.04, using enscript 1.6.5.90-2 from apt.

It seems that enscript returns 0 regardless of hitting an error:

spoolprocess@multibox:~$ enscript -o foo "fakefile"
enscript: couldn't open input file "fakefile": No such file or directory
no output generated
spoolprocess@multibox:~$ echo $?
0

Is this expected behavior for this program, an upstream issue, or something Ubuntu specific? This gave me fits trying to troubleshoot a script that processes spool files from a legacy system into PDF files for document management.
