FWIW I get different results with `cloc`:

$ git checkout REL_18_STABLE
$ git clean -dfx # be careful! this will drop your local .clangd settings etc
$ cloc ./

Overall, there is a 4% increase according to this tool. What is
convenient about `cloc` - you can count only what you want, e.g. code
without comments, etc.
