[PATCH/RFC 0/2] Automate updating git-completion.bash a bit

I noticed --recurse-submodules was missing from git-grep complete list. Then I found a couple more should be on the list as well and many more in future may face the same faith. Perhaps this helps remedy this situation?

This lets us extract certain information from git commands and feed it directly to git-completion.bash. Now long options by default will be complete-able (which also means it's the reviewer's and coder's responsibility to add "no complete" flag appropriately) but I think the number of new dangerous options will be much fewer than completeable ones.

This is not really a new idea. Python has argcomplete that does more or less the same thing.

This is just a proof of concept. More commands should be converted of course if it's a good thing to do.
