I'm pulling out my hair trying to find a gentle but thoughtful explanation of the syntax and meaning of hunk strings. I've looked on page 64 (which is brief) and scoured the internet but am coming back empty.

I'm baffled why "the first line (-1)" would be a negative number. I'm also baffled how git diff knows how many lines to include in a hunk.

Maybe I'm in a google filter bubble or something. Do you know something that explains hunks?
