- asyn-thrdd.c: scope an include. - apply more clang-format suggestions. - tidy-up PP guard comments. - delete empty line from the top of headers. - add empty line after `curl_setup.h` include where missing. - fix indent. - CODE_STYLE.md: add `strcpy`. Follow-up to8636ad55df#20088 - lib1901.c: drop unnecessary line. Follow-up to436e67f65b#20076 Closes #20070
