The content of this strbuf is unconditionally detached several lines
before the strbuf_release() and the strbuf is never touched again after
that point.

Notes:
    I'm on the fence about this change. On the one hand, I spent extra
    cycles studying the code to determine if the strbuf was used again
    after being detached. On the other hand, the strbuf_release() at the
    end of the function protects against a leak if someone ever inserts
    code which re-uses the strbuf. So, I wouldn't be bothered if this
    patch is dropped from the series.
