  Log Message:
  -----------
  [clang-format] do not break before { in JS comments

In JavaScript some @tags can be followed by `{`, and machinery that parses
these comments will fail to understand the comment if followed by a line break.

clang-format already handles this case by not breaking before `{` in comments.
However this was not working in cases when the column limit falls within `@tag`
or between `@tag` and `{`. This adapts clang-format for this case.
