bug#7254: [patch] making md5sum's --quiet and --warn independent, plus some comments

[Benno Schulenberg]

Hi,

When the command 'md5sum -c longlist --quiet' would result
in the message "WARNING: 1 line is improperly formatted",
then the subsequent command to find out which line is wrong
'md5sum -c longlist --quiet --warn' results in an unexpected
barrage of output.  It would be much nicer if --warn did not
undo the effect of --quiet, so the report of the misformatted
line does not get swamped in a long list of okays.  Attached
first patch makes this change.

(To be fully logical, the above probably has to be extended
to make --status always override --warn and --quiet and not
be overridden by them, otherwise the order '--warn --status
--quiet' would do something else than '--quiet --status 
--warn'.)

The second patch improves the description of '--warn'.  In
my opinion the option is always useful, not only when just a
few lines are misformatted -- and it would be handy if it were
the default.

By the way, why is there a short option for --warn, but not
for --quiet and --status?

Regards,

Benno
