Now that copy mode copies the pane content rather than keeping a

reference to it, it isn't necessary that the pane in copy mode is the
same as the one copying from. Add a -s flag to copy-mode to specify a
different pane for the source content. This means it is possible to view
two places in a pane's history at the same time in different panes, or
copy from a pane's history into an editor or shell in the same pane.
