Revision 38bdf62b738bb93f7e1a6af8058dc31f27c91d4e authored by René Scharfe on 01 October 2017, 14:45:45 UTC, committed by Junio C Hamano on 02 October 2017, 04:14:07 UTC
strbuf_addf() can be used to add a specific number of space characters by using the format "%*s" with an empty string and specifying the desired width. Use strbuf_addchars() instead as it's shorter, makes the intent clearer and is a bit more efficient. Signed-off-by: Rene Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
