[PATCHv4 0/6] Fix path bugs in submodule commands executed from sub dir

[Stefan Beller <sbeller@google.com>]

v4:
* addressed Junios comments in patch 1&2, which is:
1)
    * reworded commit message
    * when writing the commit message I discovered a new way to fix the bug
      (fix the computation of the displaypath instead of its parameters
       wt_prefix and prefix.)
    
      The result is the same, but I am not yet sure if I like it more.

2)
    * Use `git -C <path>` instead of `cd <path> && git`.
    * Reword commit message

v3:
Resending without `test_pause` in the last test.

v2:

The first 3 commits are
* Test and bugfix in one commit each
* better explained than before

The expansion of an expected test result moved to the back of the series.

There are two new commits
* one being another bugfix of the display path for `submodule update`
* another test for `submodule update` as I suspect it may break further on
  refactoring and we currently have no tests for it.

Thanks,
Stefan
