[Ranger-users] Top column lines go missing after executing ":set draw_borders=true"

[Gary Johnson]

In commit d7f3d7dc8631abe931a1205f12d7f11e9929f1fb, the top line of
each column goes missing when ":set draw_borders=true" is executed.
The top line of each column is overwritten by the top border line
and the contents are not shifted down.

For example, in the ranger directory (the top-level directory of the
git repo), execute

    ./ranger.py -c

The top of the display looks like this:

    address@hidden:/usr/local/src/ranger-git/ranger/build
     ranger    build                     2   lib                                
    
     README    doc                       9   scripts-2.7
               ranger                   12 
               scripts                   2 
               CHANGELOG            9.85 K 
               COPYING              34.3 K 
               install_log.txt        14 K 
               Makefile             2.85 K 
               ranger.py            1.37 K 
               README               3.58 K 
               setup.py             1.77 K 

Now execute ":set draw_borders=true".  The top of the display now
looks like this:

Opening the editor on a file and returning to ranger will correct
the display so that it looks like this:

Executing ":set draw_borders=false" has no immediate effect.  Moving
the cursor refreshes the screen, but the column contents are not
shifted back up to fill the space where the top border was.

This is probably not a big deal for most users because it works fine
if you set draw_borders in rc.conf, but I haven't decided whether I
like the borders yet, so I go back and forth from the command line.
