When we have both space and `+` we get warning "flag ' ' is ignored when flag
'+' is present [-Wformat]" https://godbolt.org/z/Weh146a5o. Should I still add
tests for this? If I add tests, should I disable `Wformat` in RUN command or
make it `// expected-warning`.
I added tests with multiple spaces after `%` - they are ignored.
