Weird indenting behavior on *.qdocinc file

When editing a *.qdocinc file an hitting <Return> the line is not continued as expected in column 0. Instead, Qt Creator seems to follow some logic meant for programming languages.

How to reproduce

Open e.g. qtdeclarativesrc/quickcontrols/doc/src/includes/zero-based-months.qdocinc in Qt Creator.
Add a newline in the text.

What to expect

As this is just text, the cursor should now be in column 0.

What happens

The cursor is moved to the left, but by about 10 characters.
