pmap avoid SEGV potential with new X/XX detail options
While permissions suggests that /proc/#/smaps contents
are world-readable, in practice this file might not be
available to a non-root process. Whether this is a bug
in the kernel or an intentional design decision really
makes no difference. This commit will protect pmap -X.
(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)
