No, (a) that read $LINE should be read LINE and (b) echo "foo
bar" | something
should preserve the quoted newline.
Ssh does seem to be consuming stuff from the inherited piped stdin
even though it isn't obvious what it does with it in a non-interactive
scenario.  But anything that reads stdin inside the loop would cause
that (throw a 'cat >dev/null' in...).
