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.
