Nautilus: How to shrink very wide Name column?

[Colin Law]

To replicate my problem, in Ubuntu 11.10 or 12.04, open nautilus and
switch to List View.  Expand the Name column by dragging the column
divider.  Now shrink the window width so there is not room for the
complete name column width.  The question is how to shrink the Name
column again without making the window wider.  I suspect I am missing
something obvious.

This can be a real problem as the column resizes automatically on
entry to a folder so if the folder contains very long file names so it
may be difficult to increase the window width enough.
