I also see these failures on alpha.

I have debugged this issue a bit: these failures happen only when useFormat is
false in function testPrint, at log_test.go:48. It looks to me that Println
doesn't handle long and short file names correctly.  Equivalent Printf function
works without problems, outputting correct expected strings.
