What version of git are you looking scanning? Commit 8989e1950a (2.21.0-rc1) has the following:
err = lstat(fullname.buf, &st);
if (show_deleted && err)
...
You may be correct that the following check:
if (show_modified && ie_modified(repo->index, ce, &st, 0
may need to include !err. Is that your conclusion? Is there a test case you have to demonstrate this that I can include in the test suite?
The patch would be (subject to my bad mailer messing it up):
diff --git a/builtin/ls-files.c b/builtin/ls-files.c
index 29a8762d46..fc21f47954 100644
