Date: Sat, 28 Nov 2015 14:42:36 +0100

Subject: [PATCH] add comment about why the ugly one-line remote command is as

 it is

In case anyone looks here for the details:

 * tcsh doesn't support multi-line strings,

   which is why it's a one-liner.

 * tcsh doesn't do 2>&1, and fish doesn't do

   'command || command' which is why we're runnig this under

   sh (which is very likely to be a POSIX shell on any vaguely

   Unix-like system)

 * The 'cd' is there to make sure we're in the home dir, because

   there was a bug report about having a cd in ~/.bashrc that resulted

   in a .ssh being created elsewhere.

 * the 'exec' ensures that we're not relying on anything beyond the

   (hopefully POSIX) shell that's available as 'sh' on the remote system
