pexpect gives as raw data going to a terminal. This means that if the completed line does not fit the emulated line, the returned data will contain line breaks. On my machine these line breaks happened to be inside the "iohandler/completion" string that the test was searching for. Work around this by telling pexpect to emulate a very wide terminal. llvm-svn: 370054
