Sorry for the delay.

You are right, this is sort of weird.  

"default" is equivalent to `"eof" or "timeout"'.

If you want to do the same thing in both "eof" and "timeout" conditions,
then use "default" instead (just to save typing).

I don't think the code above, although redundant, will cause any harm. 
Probably the default clause will take precedence for being specified
first, so the timeout clause is never used.
