Git submodules are visible in source tree, but are not valid links

Somewhat related to #206

9aea005 implemented filtering commit entries from ls-tree. It seems that this stopped working.

See freertos_kernel:
https://elixir.bootlin.com/amazon-freertos/latest/source
https://github.com/aws/amazon-freertos - it's a submodule here

Clicking on the submodule link redirects to directory that's above submodule entry.

script.sh list-blobs is not being used to list directory entries. It is script.sh get-dir. This command is not affected by 9aea005. Implementation:

elixir/script.sh

Lines 88 to 95 in 5c88c88

	get_dir()
	{
	v=`echo $opt1 | version_rev`
	git ls-tree -l "$v:`denormalize $opt2`" 2>/dev/null |
	awk '{print $2" "$5" "$4" "$1}' |
	grep -v ' \.' |
	sort -t ' ' -k 1,1r -k 2,2
	}

This is called inside Query.query():

elixir/query.py

Lines 144 to 152 in 5c88c88

	elif cmd == 'dir':
	# Returns the contents (trees or blobs) of the specified directory
	# Example: ./query.py dir v3.1-rc10 /arch
	version = args[0]
	path = args[1]
	entries_str = decode(self.script('get-dir', version, path))
	return entries_str.split("\n")[:-1]

Once we can let each project do its own custom Git fetching, we might want to error out if we find submodules. That way, we don't let any slip through and we do custom fetching everywhere it is required.
