cleanup: use clang-tidy to add missing {} around one-line statements I find this easier to read. Cleanup performed like this: hg files 'set:(**.c or **.cc or **.h) and not "listfile:contrib/clang-format-ignorelist"' | while read f ; do clang-tidy -fix -checks=readability-braces-around-statements $f -- $(python-config --cflags) -Imercurial/cext -Imercurial done make format-c I had to revert chg/chg.c as it's got a construct that seems to confuse clang-tidy, so I'll work on that file later if this change is acceptable. I only tackle files that are under clang-format's authority because otherwise I'd have to do a bunch of manual formatting. A few files didn't get edited because clang-tidy couldn't find some headers. Again, I'll figure that out later assuming this change is accepted. No check-code rule added for now because writing the regex sounds hard. In a perfect world I guess we could write a test that uses clang-tidy on these files, but I think clang-tidy is pretty rarely installed. :/ Differential Revision: https://phab.mercurial-scm.org/D5675
