You need to change umask not just for git, but for your editor and compiler
when you are working in the shared work tree as well, no? So what about
teaching your *shell* to change it as appropriate?

In zsh if you define a function chpwd, it will be called whenever you change
current working directory. If you define it as:

chpwd() {
    # The / at the end is to make foo/* match path foo
    case `pwd`/ in
	/path/to/your/worktree/*) umask 002;;
	*) umask 066;;
    esac
}

would make any command (ie. git, editor and compiler/make/...) ran from the
shared worktree run with umask 002 (or whatever depending on permissions you
want there) and anything ran from anywhere else use your normal umask 066.

I don't use bash, but I am almost sure you can get a suitable hook there as
well. If nothing else I recall there is a way to run a function from prompt
expansion, which would do the trick.
