Issue with echo blank lines

[jcubic]

There is inconsistency:

term.echo('\n');

prints 2 blank lines, the same as this:

term.echo('\n\n');

but:

term.echo('');

prints nothing

[jcubic]

Something to consider should extended commands after remove print the line? term.echo("[[ foo ]]").

Maybe just fix less plugin (that was used when founding this issue) to use:

str.replace(/^$/gm, ' ') to don't have blank lines, or maybe make it work in this way if string is empty don't print anything but if not print every line.
