Error on Multiline-Output

When I run a command, that have Multiline-Output I get an Error:
```
.\main.go:6:21: newline in string
.\main.go:6:21: syntax error: unexpected newline, expecting comma or )
```

Line 6 in main.go is the import to this libary.

Reproduce the reported command with multiline output and inspect the generated main.go around line 6, where the import is reported. Trace how multiline output is passed into the generated Go source; done when the same command no longer produces the newline-in-string and unexpected-newline errors.
