Ok, thanks. I didn't understand the explanation, to be honest, as I know
nothing about terminals/ttys.
To my naive understanding the behaviour is still different from that of
other utilities. For example when I use an invalid command with sed, its
stderr output is still well-formed in unix terms, with just an LF at the
end of every line.
cat textfile | sed -e 'crash' 2>tempfile
It isn't clear to me why Vim in batch mode doesn't produce similarly
well-formed lines. I'll try to read up on this.
