Determine if directory is under git control

Question

How can I tell if a given directory is part of a git respository?

(The following is in python, but bash or something would be fine.)

os.path.isdir(\'.svn

If you'd prefer to look for a .gitdirectory, here's a cute way of doing that in Ruby:

require 'pathname'

def gitcheck()
  Pathname.pwd.ascend {|p| return true if (p + ".git").directory? }
  false
end

I'm unable to find something similar to ascend in Python.
