top: do not co-mingle strings/numbers under namespaces

Browse Source 
Craig's recent commit under that newlib branch dealing
with namespace support has prompted me to review top's
handling of those fields. Currently, when such a field
is zero, top displays a dash ('-'). This will mean the
justification toggles ('j/J') will behave incorrectly.

This patch simply allows the potential zero to display
or be suppressed with the already existing '0' toggle.
