Describe the bug

I think this might be more of an issue with the upstream libgit2 library maybe but hunk staging doesn't work as I'd expect. e.g. in Lazygit I'm able to stage and unstage individual lines even. Perhaps this isn't representative of a canonical "hunk" in a git sense, but it's a bit restrictive e.g. if I have some staged changes and make some other changes elsewhere in the file, then stage said changes, they become part of the same hunk when it's not clear why

Steps To Reproduce

(un)staging granularity

1. Create a file with 10 lines of text and commit it
2. Change 3-4 unrelated lines and attempt to stage one of them
3. All changes are staged

Hunks unexpectedly merged

1. Create a file with 10 lines of text and commit it
2. Change the first line and save the file
3. Stage the change
4. Change the last line and save the file
5. Stage the change
6. Hunks are merged

Expected Behavior

See above

Will take a look, stage and unstage logic is implemented by me because libgit2 doesn't support apply a hunk yet. Literally, this is my bug :D

@ceuk, Please enter visual mode (Pressing v) for lines stage/unstage. Hope this solve your problem

@SuperBo that is so cool. What a great idea! Works a treat

@ceuk, I work my ass off for this line stage/unstage feature because Libgit2 doesn't support it natively :)).
