This is almost certainly the problem.  When I tried this under Cygwin
with a DOS-style patternlist.txt, I reproduced the behavior; when I
converted it to Unix-style, all was well.  I'd guess that the CR at the
beginning of the first line is being treated as part of the pattern.
Just why the other CR is not, is a question.
