I've a submodule located in a subdirectory
({git_rep}/home/{directory}/{submodule}), and I wanted to move the whole
directory up a level ({git_rep}/{directory}/{submodule}). But when I
used 'git mv {directory} ../' the '.gitmodule' file didn't get modified.

Thanks for the bug report!
Which version of Git do you use? (Did you try different versions?)

I think I can reproduce the problem. A regression test (which currently fails)
could look like

diff --git a/t/t7001-mv.sh b/t/t7001-mv.sh
index 4008fae..3b96a9a 100755
--- a/t/t7001-mv.sh
