This backports pre-dwm-5.3 behaviour where the status bar content was read from
stdin instead of the root window title. I did this, because I had several
problems with the "new" method, on different machines, with different
configurations, including vanilla, where the statusbar froze.
It adds some LOC, but is not broken for me.
