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

From: Anders Waldenborg <anders@0x63.nu>
Date: May 20, 2008, 20:55 UTC
Message-ID: <g0vdse$rj6$1@ger.gmane.org>

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.
