msg: simplify the line_skip calculation

Browse Source 
Make it more straightforward by always calculating top offset first
instead of having two branches, that tries to calc it directly.

This also fixes missing negative check before `\033[%dA` which was in
practice only problem on macOS which was handling negative values, while
in fact it shouldn't.

Fixes: #13484
