So you want a list of any number that
occurs in the file, if it occurs at the
start of the line, or is preceded by a
space character?  And you don't want
any duplicates in the list?  Is the order
of the results important?  That is, would
a result of 16,20,2,0,7 be acceptable?
Or how about 20,2,16,7,0?
