I would also consider the alternative of creating a SafeLineReader that 
can be stacked on *any* IO object (or rather any object that implements 
#read with the proper protocol) as input stream much the same way Java 
streams can be stacked.  You gain flexibility but of course you loose 
the easy "I just need to open a file and it works".  I do not have a 
clear bias either way because I love the simplicity of Ruby's IO classes 
but on the other hand you can also stuff too much into a single class.

Yet another alternative is to put your code into a Module which you can 
mix in to any IO object.  You can still decide to to that on a general 
basis for class IO and StringIO.

Just my 0.02EUR...

Kind regards
