telnet: fix strage blank spaces at beginning of telnet lines
Sometimes we saw two strange blank spaces at the beginning of the telnet lines. progress ogress > This patch fixes this problem: progress progress > The code changes are *reasonably* clean, but perhaps it could be made a bit more elegant, but I didn't want to change things after I finished diagnosis/testing & submitting the patch. The problem was that logging can send the text and the newline separately in two different requests and the telnet code would incorrectly remove the prompt from the end of a line.
