Small bugfix, two chars needed to be substituted.

Interesting fix, because I only caught this when someone ran a style
guide bot on my code, which suggested a non-sensical change of course.

It was also interesting to have a good example of why the style guide is
"wrong" for a number of reasons. Someone should patch that instead :)
