If we have `submodule.diff = log' in the configuration file
or `--submodule=log' is given as argument, range-diff fails
to compare both diffs and we only get the following output:
Submodule a 0000000...0000000 (new submodule)
Even if the repository doesn't have any submodule.
That's because the mode in diff_filespec is not correct and when
flushing the diff, down in builtin_diff() we will enter the condition:
if (o->submodule_format == DIFF_SUBMODULE_LOG &&
(!one->mode || S_ISGITLINK(one->mode)) &&
(!two->mode || S_ISGITLINK(two->mode))) {
show_submodule_summary(o, one->path ? one->path : two->path,
&one->oid, &two->oid,
two->dirty_submodule);
return;
It turns out that S_ISGITLINK will return true (mode == 0160000 here).
Similar thing happens if submodule.diff is "diff".
Do like it's done in grep.c when calling fill_filespec() and force it to
be recognized as a file by adding S_IFREG to the mode.

v2: Add test to make sure we don't regress
v3: Extend commit mesage with better explanation and base it on maint branch
since it's a bug fix
