i'm staring at this and other similar hunks and fail to see any change - probably replaced a tab with a space or vice versa ?

That is weird, this was not in the git diff and I did not change a single thing on this besides the function name changes. Maybe GitHub is using a different diff algo?

unlikely. could it be that you use a mac or windows pc and newlines \n were replaced with \r or \r\n, only on lines you touched ?

it's the other way round - your editor replaced existing CRLF with LF. to find out
i condensed your commits into a single one (git rebase -i) and made a format-patch, which i then opened with hexedit.

Then it makes sense this diff, although it sure is not showing in the diff localy. Btw, it doesn't make sense, so far all files I tweaked (not only the ones I made PR), all of them are LF, why a random file is CRLF?

I'll "fix" this tomorrow. Thanks for finding this issue

although it sure is not showing in the diff localy.

that's likely because this PR consists of like 5 separate commits, i didnt see it either before i squashed them all together.

all files I tweaked (not only the ones I made PR), all of them are LF, why a random file is CRLF?

i think the file is a mix of CRLF and LF, most editors and tools don't care about it so it flies below the radar, but when a line is touched or added that line is changed to the editor's default. fixing it (to keep diffs minimal) either requires using a hexeditor that can insert new bytes at arbitrary positions such as hexedit, or squashing the commits into one like i did, and either 1) creating a format-patch, and removing the hunks with the line-end changes with an editor, then deleting the old commits and applying the patch, or 2) unstage the changes, and selectively re-adding hunks with git add --patch, which is likely more practical since the text gui allows to shrink hunks that span over multiple blocks with s.
