I like the idea, but your patch adds two subprocess invocations to the
shell startup path. Each one takes ~200ms, and we can't afford to add
any more.

Instead of examining the group list, you can use something like

local isadmin=0
[[ -w / ]] && isadmin=1

or

local isadmin=0
[[ -w /cygdrive/c ]] && isadmin=1

Of course, that test assumes that only "administrators" can write to the
drive root, and that's an imperfect proxy for administrative rights. You
get the idea though: try to perform the test in pure bash code.
