inncheck improvements

OK, that works for me.

The only thing I changed is how the check of "--fix" is handled in your 
proposal ("inncheck --fix" does not report an error) whereas it used to do:

We previously had:

% inncheck -f
Usage error: Can't use `-fix' without `-perm'.


I have changed your proposal:

 > +&Usage("Can't use `-fix' with `-noperm'")
 > +    if $fix&&  !$perms;

to keep the current behaviour:

+&Usage("Can't use `--fix' without `--perm'")
+    if $fix && $perms < 1;


I hope that's fine for you.

It will be proper with "--perm", "--fix", etc. in our documentation.
Changes committed to checklist.pod and inncheck.pod.
("-perm" and "-fix" are still valid.)



> NB: manpage and Usage() didn't agree on "-perm" vs. "-perms"

Now "--perm" everywhere.

Updated to:
$program [-afqv] [--noperm|perm] [--pedantic] [file | file=value...]
