ps: that restored aix behavior gets its ultimate tweak

Now that this 'c' variable initial assignment has been
moved outside the looping code, there is no longer any
need to specifically check for space/comma when 'c' is
not '%'. So, let us eliminate those two lines of code.

[ i promise not to change this algorithm ever again! ]
