When user edits the patch in "git add -p" and the user's editor is set to strip trailing whitespaces indiscriminately, an empty line that is unchanged in the patch would become completely empty (instead of a line with a sole SP on it). The code introduced in Git 2.17 timeframe failed to parse such a patch, but now it learned to notice the situation and cope with it. * pw/add-p-recount: add -p: fix counting empty context lines in edited patches
