Using <CRTL>+<RETURN>, multiple selections can be make in dmenu, each
outputting on a new line. If multiple selections are made in dmenu_run
then multiple lines will be piped to $SHELL which will not be properly
handled.
This patch only pipes the last line of the output of dmenu to the shell.
In effect, the last or only program you selected is run.
I think its quite unintuitive that dmenu can output multiple lines, but
I understand removing the feature may break some users' scripts. Perhaps
a command option could be added to dissable multiple output.
