My bad for committing https://github.com/llvm/llvm-project/pull/164046/commits/ef97725a4fcdc2559a4c6451d71898f40b7437fe directly when I actually meant to do suggest edit. Not an excuse but in the other code review tool that I'm more familiar with, editing a file directly gives suggested edit.. 

The commit itself means to use bracket following https://github.com/llvm/llvm-project/blob/a3557c3abde66c7001f12f6fec7a13885574e55a/llvm/docs/CodingStandards.rst?plain=1#L1732-L1740

LGTM except the nits.
