[PATCH 0/3] t7400-submodule-basic.sh cleanups

[Jonathan Nieder <jrnieder@gmail.com>]

The 'update --init' test from t7400 is failing on a few machines
I don’t have access to.  It’s hard to say what the dangerous
ingredient is --- maybe a libc bug or something. [1]

I took the opportunity to clarify what some of the tests do and to
make the output a little more helpful.

This series has three patches for easier review, but it might make
sense to squash them; alternatively, it might make sense to split the
test into several files.

What do you think?

Jonathan Nieder (3):
  t7400: split setup into multiple tests
  t7400: clarify 'submodule add' tests
  t7400: clarify submodule update tests

[1] You can see some logged test failures at [2] [3], though it isn’t
very illuminating.  Well, that’s more of something for a Debian
Developer or someone with access to a similar machine to investigate.
