Subject: [PATCH 9/9] top: make rcfile immune from a potential locale change

The delay interval is kept in the rcfile in a floating
point format and is thus susceptible to changes in the
locale between invocations. So values written as #,###
could not be read if a new locale uses decimal points.

This commit takes control of our own decimal point and
will henceforth make top immune to locale switcharoos.

(now that we know a '.' + 2 spaces is squeezed to one)
(everything's perfectly justified, but it's just luck)
