Bug#165099: dpkg man page: --no-act non-optimal

[Andreas Mohr <andi@rhlx01.fht-esslingen.de>]

Package: dpkg
Version: 1.10.4

The dpkg man page says:
       --no-act
              Do everything which is supposed  to  be  done,  but
              don't  write  any changes. This is used to see what
              would happen with  the  specified  action,  without
              actually modifying anything.

This is not perfect, since it doesn't mention that it's a "dry run"
and a "simulation". Thus in many cases a slightly ignorant search won't
be able to find this parameter immediately.
(often you simply don't know that it's just called "--no-act")

IMHO this could be rewritten to:
       --no-act
              Do everything which is supposed  to  be  done,  but
              don't  write  any changes, just simulate them ("dummy action").
	      This is used to see what would happen with the
	      specified action, without actually modifying anything
	      (also called a "dry run").

Is there any other parameter name frequently used for this purpose ?
I know of:
--no-act
--dry-run

Other possible parameter names should be reflected properly, in case they
introduce some similar words such as "simulate" or "dry run"
that one might search for.

Thanks !
