[PATCH] D80947: Add to the Coding Standard our that single-line bodies omit braces

[Hubert Tong via Phabricator via cfe-commits]

hubert.reinterpretcast added inline comments.

+statement is accompanied by a comment that loses its meaning if hoisted above the if

----------------
I'm happy with the implications of how this is phrased, but I am not sure it was intended. A statement that is not going to be a single line (a loop inside an else) qualifies for braces.

+    handleVarDecl(D);
+  else {
+    // In this else case, it is necessary that we explain the situation with this
----------------
I believe this is an example of bad style. Applying the prose text to the example:
Adding braces in this example to the above bodies do not introduce "meaningless lines of code" as the lines already occur regardless. Adding braces may arguably improve readability.

Say, for the following, the lack of uniformity in the use of braces is a distraction:
```
if (A)
  zip();
else if (B) {
  foo();
  bar();
} else
  hello;
```
