By the way, it is common to either have following patches to be chain
reply to first patch, or better provide cover letter for patch series
and have all patches be reply to cover letter.

This is not necessary, I think; this change stands alone as a style
(semantic) cleanup.

Hmmm... that reminds me: this if-elsif chain is a bit ugly, but would
be hard to replace without given ... when, I think.

This is also ugly, but this one could in theory be replaced by hash
lookup. But this would remove symmetry...

Another solution would be to use
+
+ my $diff_classes = "diff";
+ $diff_classes .= " $diff_class" if ($diff_class);

The above is word-wrapped. Please turn off word wrapping in the
future to avoid such damage to the patch.

This would be instead
+ return "<div class=\"$diff_classes\">$line</div>\n";
which is a bit more symmetric.
But that is just a matter of taste.
