Which makes it very hard to see what you are actually changing and
whether it is a bug. It certainly looks like one but the changes muddled
in with a random subset of format fixes (even in the area patched only
some style is fixed) looks pretty clunky - surely a for() loop would be
far cleaner.


But yes agreed - its a bug, it wants fixing and style can be sorted later.
