Well, normally (if there are no problematic ABI changes) the report will
be empty. So I wouldn't spend too much time on the formatting. If
there is a violation, you can just show the raw abidiff output inside
<pre> or whatever.

Generally, this looks like the right direction.

As an additional tip, check the Python source code, they are doing
something like that with libabigail as well.
