There is a simpler solution: Let the computer fix it.  To express the
pattern in Perl: display "$1 $2" if($ref =~ /^(\d+)\s*(.*)$/);  This
means that if there is a series of digits followed by an optional space
followed by any characters; display the digits, a space followed by the
remaining characters.

Of course, there would be variations of this basic pattern.  However,
the point is that whether there are spaces or not is easy to fix.  The
output is even up to the renderer.

Just let the computer fix it.
