A flaw with the previous patch is, if there is a single long ref name,
the rest of the ref list will be aligned with the big column, wasting
lots of space (and potentially be wrapped around by the terminal, making
it even harder to read).
This patch tries to mitigate that. If there are five consecutive refs
whose name is at least ten chars shorter than column width, the width is
reduced by ten. Five and ten are picked out of thin air. But the short
width reduction (instead of "REFCOL_WIDTH = len") is to avoid the column
width being reduced then grown back too much and too fast (imagine the
next ref is really short then the ref after that is super long).
