Details:

grog has a triply-redundant system for complaining about nonexistent file
operands.


$ grog nonexistent
unknown file name: nonexistent
/usr/lib/groff/grog/subs.pl 327: grog: can't open 'nonexistent': No such file
or directory
/usr/lib/groff/grog/subs.pl 432: grog: can't open 'nonexistent': No such file
or directory


And in a Charlie Sheen win, the exit status is zero.
