Calling access() changes the CWD to $GL_REPO_BASE!
This causes a problem in the update script -- you're suddenly in the
wrong directory after calling access()!
This is actually happening inside load_1(), so fix that.
(1) testing is very easy, just run this from a clone
t/g3-clean-install-setup-test
BUT BE WARNED THIS IS DESTRUCTIVE; details in t/WARNING
(2) install is equally simple; see 'INSTALL' in the main directory
The rc file used to be a bunch of variables, each one requiring to be
declared before being used. While this was nice and all, it was a
little cumbersome to add a new flag or option.
If you disregard the "catch typos" aspect of having to predeclare
variables, it's a lot more useful to have all of rc be in a hash and use
any hash keys you want.
There could be other uses; for instance it could hold arbitrary data
that you would currently put in %ENV, without having to pollute %ENV if
you don't need child tasks to inherit it.

NOTE: I also ran perltidy, which I don't always remember to :)
