Typo: s/easiser/easier/
This paragraph could have been written better, perhaps by dividing it
in two sentences: one talking about collecting/factoring common code,
one talking about moving from presentational HTML (<i>, <b> tags) to
styling using CSS and class attribute.
Do I understand it correctly that this was meant as pure refactoring,
i.e. that none of gitweb output should have changed? Because you made
a mistake, and 'log' view is broken (and it doesn't look like it did
before). See comments below for cause and (simple) solution.

Good... although I wonder if we should not get rid of chop_and_escape_str
altogether, and for example add title attribute (if needed due to having
to do shortening) directly to $tag, and not to inner <span> element.
Should "\n" be in returned string? Just asking.

Nice using of hash to have named optional params.
Usually though we use %opts and not %params for the name of this
hash, and we use CGI-like keys prefixed by '-', for example
'-z' in parse_ls_tree_line(), '-nbsp' in esc_html, '-nohtml' in
quot_cec(), '-remove_title', '-remove_signoff' and '-final_empty_line'
in git_print_log(). git_commitdiff() uses %params, but it doesn't
have non-optional parameters (still, I guess we should use %opts
for consistency), and it uses '-format' and '-single' as names.
href() subroutine uses %params... but those are not extra named
optional parameters to subroutine; they are CGI query parameters.
NOTE: Default tag (as used in git_log) should be not generic block
element tag: 'div', but rather generic inline element: 'span'. The
presentational HTML element '<i>' which we are replacing is inline
(layout) element.
It is because it is '<div>' (and probably because some "random" CSS
rules in gitweb.css match it) it breaks layout or 'log' view. There
two horizontal lines: one for <div> element, and one for unnecessary
now <br> element. As div.author_date it has extra 8px padding, from
which the top padding is visible as extra unnecessary vertical space.

Gaah, git has chosen to show this diff a bit strangely...

Typo: s/containign/containing/
You could say that it uses format used to show author and comitter fields
(headers) in 'commit' view.

By the way, what about author / tagger info used in 'tag' view?
Wouldn't it be better to factor out generating table rows for single
author / committer / tagger header (field) info?

Here you replace inline <i> element with <div> _block_ element,
destroying layout. Replacing default of 'div' by default of
inline <span> element restores old layout.

I'd rather use here (as mentioned in comment about git_print_full_authorship
subroutine) something like the following:
+ git_print_authorship_header(\%co, 'author');
+ git_print_authorship_header(\%co, 'committer');
Or something like that. But this might be a matter of taste.

Nice. Although... 'localtime' / '-localtime'? Perhaps '-show_localtime'?
But that is just nitpicking (naming is hard), and I am not sure if
proposed name is any better.
