Clear the previously written line instead of clearing the whole console window width. This way, when resizing the console window, lines don't wrap.
Here's a GIF to better understand what happens. The first two message batches use the console width (code before this commit). The last two message batches use the new code that clear only what's needed. Dots have been added (second and fourth samples) instead of spaces to better see why line wraps.
