We use <div class="pre"> in "commit" view if I remember correctly.

Good idea.

I'd rather keep RSS output as simple as possible, no frills.

esc_html does to_utf8, so to_utf8 is unnecessary (and spurious).
But it is a good catch: esc_html is certainly needed.

We have introduced esc_path for escaping pathnames. Use it!

Two unnecessary calls to git command. Use 
     my %difftree = parse_difftree_raw_line($line)
instead. The conditions would probably be 
     next if (!$difftree{'from_id'});
(or equivalent).

esc_url, not esc_html here. Or use the href() subroutine with -full=>1
option (after applying the patch I send which added this to href()).

P.S. Please reply also to git mailing list.
