Subject: [PATCH] Fix highlighting to correctly highlight things like =='aa'.
 Given the way highlighting works, this change will break highlighting for
 statements like for a in $tags:'aa' rof. I think that strings following
 operators is far more common than strings following the colon in a for
 statement.
