Fix single-line comment indentation after multi-token values in expression

After expressions, single-line comments are formatted incorrectly.

Expected:
```delphi
A :=
B.C
//
+ D;

```

Actual
```delphi
A :=
B.C
//
+ D;

```

This issue must be related to the fact `B.C` is not a single token because the following is formatted correctly.
```delphi
A :=
B
//
+ D;
```
