status is indented strangely here - should just line up with the previous L
(Could try and reformat to make other things clearer, but as-is, this
indentation is weird).

[Matt Giuca, 2015/06/09 04:10:34]

Lining up with the previous L is incorrect (it would imply that 'status' is a
parameter to UnicodeString, which it isn't).

Just reformatted this line.
