The default mode on MS-Windows is text mode, so the Windows runtime
converts \n into a CR-LF pair when it outputs the string.

When running the test suite, Grep usually comes from MSYS, which is a
Cygwin fork, and those work like on Unix: they don't convert CR-LF to
newlines on input, like native Windows programs do.

Would it be possible to use 't/infodir/file1.info\r\?$' instead?
