With this release, long lines are wrapped in side-by-side mode, thanks to a far-reaching series of contributions by @th1000s (see https://github.com/dandavison/delta/pull/515). No special customization is needed, but sophisticated control over the details is available: see --wrap-max-lines, --wrap-left-symbol, --wrap-right-symbol, --wrap-right-percent, --wrap-right-prefix-symbol, --inline-hint-style.

In the image below, the long deleted line in the left panel overflows by a small amount, and the wrapped content is right-aligned in the next line. In contrast, the long replacement line in the right panel overflows by almost an entire line, and so the wrapped content is left aligned in the next line. The arrow markers and ellipsis explain when and how text has been wrapped.
