[TxMt] odd spacing with "puts" in RubyMate

I have a Ruby script like this:

result.each do |k, v| puts "----" puts k v.each {|m| puts "\s#{m}"} end

The point is that the first two lines (of each iteration) have no space before them, but the remaining lines have a space. In Terminal the output starts out like this:

---- String % * +

That is correct. In RubyMate the output starts out like this:

---- String % * +

That's incorrect. Where's my initial space? No matter how many \s I ask for, I never get that many in the output. m.

PS I think I'm also seeing some occasional problems where a lot of puts causes the output to hang, so that I have to close the RubyMate window and get it to stop running. But I'm not able to reproduce reliably so I could be wrong about this.
