see note before, this is really about maintaining compatibility, I don't want to make the assumption that everyone likes


```
if (x) return 1;
else if (x) return 2;
else return 3;

```

There could easily be users who want this.

```
if (x) return 1;
else if (x) return 2;
else 
   return 3;
```

I don't think it over complicates it, but it keeps the flexibility. The name of the option may not be the best 'suggestions welcome'


================
Comment at: clang/include/clang/Format/Format.h:263-264
     SIS_WithoutElse,
-    /// Always put short ifs on the same line if
-    /// the else is not a compound statement or not.
+    /// If Else statements have no braces don't put them
+    /// on the same line.
+    /// \code

This is a compatiblity case for the previous "true" as it was before

Before 


```
if (x) 
   return 1;
else
   return 2;
```

would be transformed to


```
if (x) return 1;
else
   return 2;
```

but


```
if (x) 
   return 1;
else {
   return 2;
}
```

would not be transformed at all
