[PATCH] Added -d and -e options to the "git" script.

["David Kågedal" <davidk@lysator.liu.se>]

These flags override the GIT_DIR and EDITOR environment variables.

---
This is more generic way to specify GIT_DIR than Linus' suggestion,
although it is only targeted at more porcelainish usage of the git
driver script.

I needed this for the Emacs commands I've been hacking on, since it's
hard to set environment variables for single commands without
involving /bin/env or a shell.
