[PATCH] gitweb: Escape attribute in chop_and_escape_str()

Fixes the title attribute in <span title="Jürgen Kreileder">Jürgen
Kreileder</span>
for example because to_utf8() is called implicitly now.

(Not sure why the attribute is there at all in the example. From my
point of view
nothing got chopped.)
