This finally explains why I kept triggering a bug on BeeBS a year or two ago -
with CR -> CRLF disabled MuffinTerm was sending NULs after the CR and I could
never work out why.

To be fair I didn't try that hard to work it out, I just switched CR -> CRLF
on and Vela fixed the bug as well for good measure.

But, yeah - thanks for sharing :)
