Dear Erik,

Thanks very much for this patch.

I can repeat this, and confirm that your patch fixes the problem.  I'll
commit it now.

Thanks very much.  Thanks also for telling me about point 2b --"just M-x
R on the tramp-visited file to start up an R session on that host".  I
didn't know that would work, amazing!  I think this will need
documenting.

What is your preferred method for using tramp -- the scp method?

Stephen
