precompose_utf8: drop unused variable
The result of iconv is assigned to a variable, but we never use it (instead, we check errno and whether the function consumed all bytes). Let's drop the assignment, as it triggers gcc's -Wunused-but-set-variable. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
