[clang-format] Where is the indentation level determined?

I’m looking to solve bug 49352 & I’m wondering where the best spot would be to add this option (so that the lambda body indentation is relative to the parent scope containing the lambda declaration instead of relative to whatever indentation scope the lambda declaration itself was given).

I was thinking perhaps in LevelIndentTracker::nextLine, but the lambda detection there is too early & I can’t adjust the line containing the bodies or too late & I don’t know if the line is part of a lambda. Similarly, I looked at UnwrappedLineParser and tried messing with the Level a line is assigned, but that doesn’t seem to have an impact on the indentation for some reason (even though the Level should be driving the indentation, right?).

Any tips would be greatly appreciated.
