Glue does not work as expected on choices

When using glue on choices, the chosen text is still printed on a new line.

For example
```
I saw <>
 * a bird.[] etc.
 * a beaver.[] etc.
```
and
```
I saw 
 * <>a bird.[] etc.
 * a beaver.[] etc.
```
both produce
```
I saw 
a bird. etc.
```
instead of the expected
```
I saw a bird. etc.
```
