Replace carriage returns with newlines

[p3lim]

At least on windows, some applications tend to reset the cursor with carriage returns to overwrite lines. This ends up looking weird in some situations with scripts and certain programs.

Please support this either by allowing rewriting or simply replacing single carriage returns with line feeds (better solution in my opinion).

This is a very old issue, I know. :( It seems to be very shortly after #21 was fixed, so I'm wondering whether the issue is actually resolved.

Since I'm triaging all issues I'll leave this open for a bit longer.
