Bug#552085: vim-scripts: gnupg plugin fails if /bin/sh is a link to dash instead of bash

[Tim Meushaw]

I experienced the same error with this plugin.  For over a month now I 
couldn't figure out why the plugin worked flawlessly on one system but 
failed on another.  The errors I got were the same, and went away as soon 
as I switched /bin/sh to point at /bin/bash instead of /bin/dash.
