Of course that is not the alternative I was suggesting :).

If memory recalls, adding “overflow-x: auto” should cut off any 
exceeding text on the right, and make it horizontally scrollable.

(Ideally you would make the alternating bars span the entire scrollable 
width, but unfortunately that’s impossible without resorting to tables.)

Scrollbar at the bottom is a little inconvenient, sure, but you can also 
scroll horizontally with many mouse wheels, or by middle-clicking and 
moving the cursor to the right, or by moving two fingers to the right on 
a touch pad, or by selecting text and dragging to your right. The 
scrollbars are hardly ever being used any more nowadays.

I am not in favour of wrapping the source code, because that can 
visually disturb the indentation. It may not be so bad on desktop-sized 
displays, but especially on smaller screens like tablets or mobile 
phones this can render code virtually unreadable. In some languages 
(e.g. our beloved python) new lines can even significantly alter the 
meaning of code.

Emacs and vim aside, editors normally don’t wrap lines and people will 
be authoring code with this in mind. Programmers typically expect to 
exert control of where and how the lines wrap in the editor, and expect 
it to be displayed as such.
