Not the leading spaces, but the asymmetric space around '=='. (Yes, 
Thunderbird is known to have a display bug where lines prefixed with 
space show at a different indentation levels than lines prefixed with - 
or +, which makes patch review via Thunderbird a bit more awkward than 
it should be - but that's not what I was complaining about)
