I'm probably being overly pedantic, but I tripped over this failing to
mention that the strbuf is not used between the initialization and the
release. That is, I had expected it to say:

    Add a coccinelle rule to remove "struct strbuf" initialization
    followed by calling "strbuf_release()" function without any uses
    of the strbuf in between.

Did you mean "when strict"?
