As we store the config options in default_diff_options and then copy 
them across at the beginning of repo_setup_diff() we can use a flag in 
struct diff_options which is set by handle_ignore_submodule_arg() to 
tell if we need to initialize opts->flags.ignore_untracked_in_submodules 
in repo_setup_diff()

Are you adding the printf and then running t3600? If so then the extra 
line of output breaks a lot of tests which in turn breaks to setup for 
the test that was failing so there are uncommitted changes. 
Unfortunately it is hard to run a subset of tests in a lot the test 
scripts as there are implicit dependencies between the individual tests 
them.

For the diff tests I think we want to test the new default and check 
that --ignore-submodules=none works. I think for the other tests we 
probably want to just add --ignore-submodules=none

I'm afraid I'm still no closer to figuring out why that test in t3600 fails
