kill-rectangle if middle line is longer than last

[Dan Jacobson]

Assume a file contains
Disallow: /geo/taiwan_addresses/
Disallow: /geo/taiwan_datums/triangpts/twd67/penghu67.txt
Disallow: /geo/taiwan_datums/triangpts/twd67/taiwan67.txt
Disallow: /geo/taiwan_triangpts/
Disallow: /location/house_views.html
Disallow: /me/1988tcsh.txt
one can do awk '{print $2}', but one cannot use kill-rectangle to get
the same effect unless the longest line is at the end, unless one
wants to add lots of spaces to the end of the last line in order to
move the cursor far enough to grab the whole rectangle.  Alas.  Hmmm.

> Then kill $1

Very funny.
