tweaks: elide two unneeded variables 

After extracting a line or region, the current line is always the one
where renumbering should start.  And when ingrafting a buffer, it is
always the first ingrafted line where renumbering should start.  The
'top_save' variable was indirectly getting set to those lines.

Also, renumber immediately after unpartitioning the file buffer, before
doing anything else.
