A bug was introduced in commit 1fc82b6, when word wrapping was
introduced. The script was ignoring the user provided message.
What made it hang waiting for user input.
The bug is fixed now. Who could imagine that just a pair of quote
marks could break the script like that...
I didn't like the script written in python. I feel like I didn't do
it quite right. The mess with pipes confuses me. It is so much
simpler to handle pipes using shell script, in my opnion.
The shell script version of 'pokemonsay' is tiny if compared to the
python version. And it does the same thing.
