Re: [PATCH v4 1/9] submodule absorbgitdirs tests: add missing "Migrating git..." tests

[Glen Choo <chooglen@google.com>]

No comment on the structure of the tests themselves; those look good to
me.

I thought that we typically avoid setting environment variables in the
test cases themselves, so when we set environment variables to be read
in later tests, we typically set them outside of the test case (e.g.
t/t5526-fetch-submodules.sh).

DO_IT is a leftover from dev?

(I'm also curious as to what it does :)).
