I've expecting that comparing snippets will just look at a block of text - or each line at a time - to make sure the partial config item is the same on the comparing download and the previous version.
But if I put a config snippet which has lines 10-30 in the full config, the compare will run. But the line numbers are wrong. It will mark lines 1-9 as missing, 10-30 OK, and after 30 bad.
What I want compare to do is to ask "are these lines individually the same in the other text?" not what line it's in or if there's other stuff at the top which isn't included.
