# The tests ahead of each function are because I have 's' and 'r' aliases from

# I would love for this section to work; if we could get the port that gets
# used by the -R option before we hand off to the other side, then I could
# pass it somehow through and know where to connect in that shell.  But even
# though the man page says the port is "reported to the client at run time"
# that appears to only be in an echo statement.  So there will be an extra
# copy and paste step.  Meanwhile, I'm keeping this here in case I find a
# better way in the future.  This would immediately follow the function
# definition and the part that is left in that function would be in the else
# clause.
