There's a rule in strbuf.cocci for converting trivial uses of
strbuf_addf() to strbuf_addstr() in order to simplify the code and
improve performance a bit. Coccinelle 1.0.0~rc19.deb-3 on Travis CI
lets the "%s" in that rule match format strings like "%d" as well for
some reason, though, leading to invalid proposed patches.
Use the "format" keyword to let Coccinelle parse the format string and
match the conversion specifier with a trivial regular expression
instead. This works fine with both Coccinelle 1.0.0~rc19.deb-3 and
1.0.4.deb-3+b3 (the current version on Debian testing).
