🐛 CRLF line endings are stripped from diff

I'm trying to show CRLF line endings in my diffs (on Linux, to quickly spot if someone committed a file with CRLF instead of LF). Less has the option `-u/--underline-special` to do just that, so I could just use that as pager for delta. However, delta _always_ seems to strip the carriage return byte from diffs, see:


Here is a hexdump of both diffs. You can see the CR-bytes (0x0d) are missing.

Even if delta strips the ANSI color escape codes (which is turned off here with `--raw`), it should never just delete any other character from the output. Let the pager decide to show those control chars or not.

Reproduce the issue with a CRLF-containing diff on Linux, using delta with --raw and a pager that displays control characters. Trace the diff-output processing to find where 0x0d is removed; done means the carriage return bytes reach the pager unchanged while ANSI handling still works.
