The attached patch adds a new variable org-html-wrap-src-lines to
control whether code tags should be added or not.

I’m not sure whether :package-version 9.3 is correct.  Also, I set
the value to t, which does not change the current functionality.
However, for backwards compatibility (up to version 9.2.6), a value
of nil would be preferable.  Any thoughts?
