Thanks for the additional information. I can indeed duplicate that bash
is stripping \r\n to \n, but NOT stripping other \r, when reading from a
pipe:
$ printf ':\r:\r\n' | { read t; echo "-$t-"; } | od -tx1
0000000 2d 3a 0d 3a 2d 0a
0000006
and pipes themselves are not doing the stripping:
$ printf ':\r:\r\n' | od -tx1
0000000 3a 0d 3a 0d 0a
0000005
I also confirmed that raw files have the same problem. Possibly a bug I
introduced in my code to support igncr, so I'll try to root it out.
