Subject: [PATCH] gitweb: Fix chop_str not to cut in middle of utf8 multibyte chars.

From: Anders Waldenborg <[email-masked]>
Date: Tue, 20 May 2008 22:55:41 +0200

Without this fix at least author name in short log may cut in middle of a
multibyte char. When the result comes to esc_html to_utf8 is called again,
which doesn't find valid utf8 and decodes using $fallback_encoding making
it even worse.
