fix title setting bug in xterm and urxvt

Before this patch, commands containing %-signs set the title wrong (urxvt and xterm) [1] and produce strange output in urxvt [2]. test for bug 1: > sleep 10 && echo % sets title to "sleep 10 && echo %<<" > sleep 10 && echo %f doesn't change the title at all test for bug 2 (only urxvt): > echo %f 39m%f ^^^^^----- output
