This should make sure our log lines look nice even if the tty we are connected to is in raw mode. Normally, it's the TTY's job to turn an NL we output into a CRNL and interpret it accordingly. However, if the tty is in "raw" mode it won't do that. Specifically, this is controlled by the ONLCR flag on the TTY. A TTY might be in raw mode if our "ptyfwd" logic is used for example, where a 2nd tty is bi-directionally connected to the primary tty, and duplicate processing is not desired. Hence, let's just write out the CR on our own. This will make sure that whenever we output something subsequent output always continues on the beginning of the next line again, regardless the mode the TTY is in. Of course, if the TTY is *not* in raw mode, then the extra CR we now generate is redundant, but it shouldn't hurt either, as it just moves the cursor to the front of the line even though already is just there. We only to that if we actually talk to a TTY though, since we don't want the extra CRs if we are redirected to a pipe or file or so. We are not on Windows after all. Fixes: #30155
