[PATCH 1/4] utf8.c: remove print_wrapped_text()

["René Scharfe" <rene.scharfe@lsrfire.ath.cx>]

print_wrapped_text() is the only function that calls
strbuf_add_wrapped_text() without a strbuf, which then writes its
results to stdout.  At its only callside, supply a strbuf, call
strbuf_add_wrapped_text() directly and remove the wrapper function.
