When formatting Swift code using swift-format, comments from one line are improperly duplicated to the following lines.

Steps to Reproduce:

Create a Swift file (test.swift) with the following content:
```
1 // test
+1
```
Run the following command to format the code:
```
swift run swift-format test.swift
```
Check the contents of test.swift after formatting:
```
1  // test
+1  // test
```
