Subject: utf8.c: remove print_spaces()
X-Git-Tag: v1.7.0.2~9^2~2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=3c0ff44a1ee92bd0f811b95d747a08763983566b;p=git.git

utf8.c: remove print_spaces()

The previous patch made sure that strbuf_add_wrapped_text() (and thus
strbuf_add_indented_text(), too) always get a strbuf.  Make use of
this fact by adding strbuf_addchars(), a small helper that adds a
char the specified number of times to a strbuf, and use it to replace
print_spaces().
