Wouldn't strbuf_rtrim (or even strbuf_trim) be useful here?

Manipulating only a copy of the len parameter while changing the strbuf itself raised warning flags, though it is correct as-is because you never actually use sb.len.

Using strbuf_trim is shorter, easier to read, and will helpfully eat any extraneous whitespace, too.
