[patch] really fix splitting addresses in repl

[Ruud de Rooij]

Oops!

The previous patch I posted contains a bug where an empty line will be 
introduced into the header if the address contains no spaces or commas at 
all.

Here's an updated patch.

Sorry for the inconvenience.

Thanks,

Ruud de Rooij.
