Not a bug.  In Mac text files lines end in \r.  In Unix text files  
lines end in \n.  In windows text files lines end in \r\n.   
TextWrangler must save files in mac format while TeXShop saves them  
in Unix format.  You can do a search for (\r(\n)?|\n) and that will  
find end of lines in all of the text file types.
