Final manual curation in preparation for global clang-formating (#3712)
* Manual line breaks to pre-empt undesired `clang-format`ing. Informed by work under https://github.com/pybind/pybind11/pull/3683:60b7eb410f59572e6559* Manual curation of clang-format diffs involving source code comments. Very labor-intensive and dull. * Pulling .clang-format change from @henryiii's9057962d40* Adding commonly used .clang-format `CommentPragmas:` * Ensure short lambdas are allowed Co-authored-by: Aaron Gokaslan <skylion.aaron@gmail.com>
