Uh... that’s an HTML file—this is the emacs-orgmode mailing list. And
viewing that page as rendered HTML in a browser, there’s no horizontal
scrolling I see (and doesn’t appear to be with your styles as rendered at
https://cup.github.io/autumn/append-to-array/). I was asking for an example
of an Org mode file showing the issue that’s concerning you, not just proof
that GitHub sometimes does horizontal scrolling.

If you’re asking about long lines in general that could be generated as
export from Org-mode to any other format, such as Org *into* HTML, and then
want to limit the lengths of the lines of the exported document code
generated, in characters—and not what is displayed in width as pixels—then
I don’t understand why you’d even be looking at Org-mode’s own link syntax.
Line breaks in an Org file do not, in the general case, propagate into
exported formats (except when line breaks are significant, like in source
blocks). So successfully line-breaking in the middle of a URL in Org
wouldn’t necessarily generate a line-broken URL in the resulting HTML (or
TeX or PDF, source or rendered).

In any case, there will be no single solution to this—any ox library for
Org export you use will have to be modified if they don’t handle
line-breaks the way you want.

If you’re planning on including verbatim Org source examples _in_ the
generated HTML (as you are currently doing for comparing programming
languages), that’s the case where a long Org source line might bleed
visibly into the final rendered output. Are you?
