I'm trying to find lines with the carriage return character, but I'm not getting the results I'd expect. I've whittled it down to this proof-of-concept:
$ uname -a CYGWIN_NT-6.1 Aodh 2.0.4(0.287/5/3) 2015-06-09 12:22 x86_64 Cygwin $ grep --version grep (GNU grep) 2.21 Copyright (C) 2014 Free Software Foundation, Inc.

I've tried various other ways of grepping for the
\r character, but none have worked.
Notice this is on Cygwin, which certainly could be part of the problem.
