Why is the compressed bit being set in inode headers when its size is 0?

I've been reading through SquashFS documentation and I've been unable to find anything indicating that the compressed bit should be set if the size is 0, what is the purpose of this code?

https://github.com/vasi/squashfuse/blob/94f998c58d2bb6dff00173f33140a0354adce324/fs.c#L137-L138

I don't know why it's not documented, but it's what the kernel does: https://github.com/torvalds/linux/blob/50dffbf771802c4db88de2cb942affa0ada43ad0/fs/squashfs/squashfs_fs.h#L108

@vasi I asked the author of SquashFS, apparently it only pertains to SquashFS 1.0 so it should be safe to remove

Oh nice, thanks for the followup.
