[PATCH] use strbuf_addstr() for adding strings to strbufs

["René Scharfe" <l.s.r@web.de>]

Use strbuf_addstr() instead of strbuf_addf() for adding strings.  That's
simpler and makes the intent clearer.

Patch generated by Coccinelle and contrib/coccinelle/strbuf.cocci;
adjusted indentation in refs/packed-backend.c manually.
