Line numbering w/ respect to deletion

[Gladdstone]

This was mentioned in a now-closed issue. The change is to count lines with respect to line deletion by means of a delete queue as shown below.

Still familiarizing myself with the Yew framework so if you come across any glaring issues please let me know.

I think this is a good start, but it looks like it's not fully correct yet?

If you look at the screenshot, line 17 is missing.

My feeling is that we should evaluate the data structures we are using and capture line information properly, instead of "recreating" them when we render the diff.

But I will take a closer look at your PR tomorrow, when I have a fresh mind.

ty, that's my bad. The index skips ahead when you group the deletions, I'd made a note to fix it and forgotten.

I agree that modifying the construction of the change object upstream would be a much more elegant solution. I was initially concerned that might be too disruptive a change to the code but I'd be happy to look into it.
