Subject: Don't break comments after includes.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7ff96ed7336b4f0efef05c10fd5ce5143918d4e1;p=clang

Don't break comments after includes.

LLVM/Clang basically don't use such comments and for Google-style,
include-lines are explicitly exempt from the column limit. Also, for
most cases, where the column limit is violated, the "better" solution
would be to move the comment to before the include, which clang-format
cannot do (yet).
