A convenient way to pad strings is to use something like
`strbuf_addf(&buf, "%20s", "Hello, world!")`.
However, the Coccinelle rule that forbids a format `"%s"` with a
constant string argument cast too wide a net, and also forbade such
padding.
The original rule was introduced by commit:
28c23cd4c39 (strbuf.cocci: suggest strbuf_addbuf() to add one strbuf to an other, 2019-01-25)
