Splitting a hunk with magit
I have 2 edits very close by (and therefore part of the same hunk), that I'd like to commit separately. Is it possible to split a hunk from within magit?
You can set the mark correctly with Ctrl+Space (C-SPC) and magit will only commit the selected portion.
You can also use - and + to decrease or increase the extent of the hunks in the diff (and 0 resets), but dominikh's answer is the most important one to know about.
