pmap: a spade is a spade, so let's call a Flags a Perm
For some reason when the new -X/-XX options were added
what was always displayed as 'Mode' became 'Flags'. So
now a precious horizontal space is wasted because that
field's data has only 4 bytes whereas the header is 5.
Moreover, this created a conflict with the top program
which used that name in a column header already. Plus,
top emitted a 'Translation Hint' that suggests the max
chars should be 8 which is a limit pmap needn't share!
The xgettext program provides no way to keep identical
strings separate. This meant both top and pmap will be
sharing not only the msgid but a Translation Hint too.
So, the solution will now be two distinct field names.
Besides the kernel folks document it as 'perm' anyway!
