[Geary] Bug? Excerpt fails if highlight doesn't include newline char

[johnywhy gmail com]

I love the feature that if you highlight some text in a received mail, and click 'Reply', then your new compose-screen contains the highlighted text in quoted format. Awesome!

However, if your highlight doesn't contain a newline, then you don't get the excerpt. Instead, your reply appears as if you didn't highlight anything. Ie, the entire message is quoted, instead of an excerpt. 

Cheers
