Pasting within a line removes the line break at the end of it.

I imagine this is where Nightcode editor issues go. (This is in Nightcode 2.5.6 running on Windows) In this case, I pasted dependency info from github into the :depencencies vector and that seems to have removed the carriage return at the end of the line. You can see where the :aot bit jumped up to the end of the line.
