Steps to reproduce:
1. Set up a content type with two optional text fields (text1 and text2).
2. Make content with content in only text1.
3. Set up view with:
* show fields
* add text1 and text2 (with label)
* text2 should be rewritten to also include text1 as a token and to not hide rewrite when empty.
Expected output:
View with content of text1 field output next to label for text2.
Actual output:
The view will not show the content of text1 in the text2 field even though it has been rewritten to do so.
I have created a patch for this, however, the patch does not add a test that catches this problem.
