It's slightly strange seeing worktree validation in a function
checking whether the worktree is clean since submodule validation
isn't an issue of cleanliness. I'd have expected the caller to invoke
it instead:
int remove_worktree(...) {
...
if (!force) {
validate_no_submodules(wt);
check_clean_worktree(wt, av[0]);
}
...
}
On the other hand, I could imagine it being called here as appropriate
if submodule validation eventually also checks submodule cleanliness
as hinted by the commit message.

Minor: I think there was some effort recently to remove "git-foo"
style mentions from documentation and error messages. Perhaps this
could be "failed to run 'git status' on '%s'". Ditto below.

Style nit: In the very similar delete_git_dir(), just below, there is
no blank line before 'return'.

Minor: Same concern as in 3/7 about the multi-line error message
making scripted handling of error message collection more difficult.

Perhaps place 'unlock' in test_when_finished()[1].

Reversion of 'init.t' probably belongs in the preceding test which
modified it, wrapped in test_when_finished()[1].
