Oh, and as to other strbuf_* helpers, I am finding myself getting
very fond of strbuf_git_path() as I read the series along; it gives
us the same convenience as git_path() [*1*] while giving us tighter
control on the lifetime rules of the path buffer.
*1* And the new git_path() updated in this series has to be a lot
more than catenate($GIT_DIR, "/", $path) but needs the smart of
adjust_git_path(), the convenience matters.
