pin the right edge of the text to the right edge of the monitor

[Dan Jacobson]

Gentlemen, do
$ perl -wle "for (1..50){print 'z' x $((${COLUMNS-99}+10))}" > wide_file
#I.e. make a file with lines longer than your monitor can handle without 
wrapping.
$ emacs -q --no-site-file wide_file
M-x toggle-truncate-lines
C-e or C-x <
Note how there is tons of space wasted as there is no way to pin the
right edge of the text to the right edge of the monitor.
A C-a gets the left edge of the text nicely fixed to the left edge of
the monitor, but no consideration is given to us right-wingers.
