[PATCH 3/8] gitweb: Move HTML-formatting diff line back to process_diff_line()

["Michał Kiedrowicz" <michal.kiedrowicz@gmail.com>]

Commit 6ba1eb51b (gitweb: Add a feature to show side-by-side diff,
2011-10-31) for no special reason moved wrapping diff line in <div> out
of format_diff_line(). Bring back old behavior.

This simplifies code in git_patchset_body() and keeps formatting of a
diff line in one place.

The more long-term purpose of this patch is to move formatting diff
lines down to print_diff_chunk(), to allow processing lines without
HTML-formatting.

This is just a refactoring patch. It's not meant to change gitweb
output.
