I'm not convinced yet, because a single comment in only one column is
enough to show the "Description"'s column again.

IMHO it seems to me that the only gain of this new proposed behaviour
only happens when there is no especial information about the columns,
like comments or stat target, and I don't know if this is a common
situation.
