Yes, I think so. It's just for include. It's not a very good patch, I think , sorry for this .

And it has a known issue , it will include the parent node path , this is a problem. I made another program to delete parent node.

The expected dump file will include /A/subdir(revision 50) into add. But in fact there was nothing.

Then the dump file will include /A/subdir and it's subdir or subfile into add , but regrettably, the dump file will also include /A into add.

Thanks for the patch. I don't see any obvious problems with this approach. However, the patch as it stands causes a regression:

So, I guess the new condition should be applied to --include's but not to --exclude's?

Cheers,

Daniel
