Another problem is that there are those corporate server-side folks
who are interested in giving an endpoint that lets clients to ask
performing Git operations (like grep and blame). Adding more statics
instead of keeping track of dynamic runtime structure like grep_opt
is deliberately making things more difficult for them, isn't it?
