top: correct functioning of the '-p' command line args

Browse Source 
With the introduction of a new '1' command line toggle
I have gone and broken a provision of the '-p' command
line switch (pids monitoring). Multiple pids could not
be specified through the use of comma delimited lists.

Thus, this commit simply corrects that newly added bug
which was born in the 'adjustment' commit shown below.

Reference(s):
. adjustment to '-1' implementation
