remove private information from user documents

[Ingo Schwarze <schwarze@usta.de>]

Hi,

Theo noticed that mandoc(1) includes information about itself
into PostScript and PDF documents it creates.

I don't like that.  Basically, what software i'm running, and which
version, is private information about myself.  I don't expect such
information to end up in documents i'm creating.  Often, having that
information included won't matter, but in some situations, it may be
a bad idea.  Besides, leaking private information is never nice,
least so when the user is not aware what's happening and has no
obvious way to switch it off; but i'd go as far as to say that it
should not only be off by default, but that even an option to enable
it would be on the verge of bloatware.

If i want such information, along with my birthday, phone number and
address, sent out to the world, i can always choose to run Microsoft
Word.  ;-)

OK?

Yours,
  Ingo
