Comments like these end up looking like this after conversion:
```d
                const(char)* arg = mangleFunctionType(cast(TypeFunction)type.next); // compute args before checking to save; args should be saved before function type
                if (checkTypeSaved(type)) // If we've mangled this function early, previous call is meaningless.
                    return; // However we should do it before checking to save types of function arguments before function type saving.
                // If this function was already mangled, types of all it arguments are save too, thus previous can't save
                // anything if function is saved.
```
because the converter just knows they follow a statement, but not how to re-align them.  It would be better if they could be placed before the `if` instead.
