New lines wrongly marked as changed

Hi, thanks for GitGutter, I'm impressed with how responsive it is.

There's an issue with the diffs on my machine where new lines show up as changed if an adjacent line is also changed.

For example, if I insert to lines with no other changes, then things look right (I need to tweak the colour):

But then if I change an adjacent line, those new ones are also shown as 'changed':

I am using the unix diff tool to determine the changes against the repo at HEAD. I believe that is just how unix diff treats changes, if new lines are touching modified lines, they are all treated as a single modified code block.

Ahh, right you are. I wasn't thinking in terms of a diff :)

I experimented with diff -y, which does distinguish between changed and
inserted lines, but its output would be harder to parse. (Even if it
weren't in two columns, which makes it unfeasible.) I also checked out
line-format and group-format, which looked promising but ultimately I don't
think it's worth pursuing.

In the end, the diff is generated by comparing old and new equally, and so
is never going to produce what might be the most logical description of
just the new, non-diff lines.

Cheers,
Ben
