Make R_NULL not repaint and document the fact that this means some keybindings need to manually tell fish to repaint

@ -1091,7 +1091,11 @@ You can also bind a pice of shellscript to a key using the same
syntax. For example, the Alt-p functionality described above is
implemented using the following keybinding.
<pre>"\M-p": if commandline -j|grep -v 'less *$' &gt;/dev/null; commandline -aj "|less;"; end</pre>
<pre>"\M-p": if commandline -j|grep -v 'less *$' &gt;/dev/null; commandline -aj "|less;"; end;</pre>
If such a script produces output, the script needs to finish by
calling 'commandline -f repaint' in order to tell fish that a repaint
is in order.
