When you hit enter, that puts a \n character in the buffer. readf 
doesn't skip that automatically, so it complains upon hitting 
that newline (the error message shows the character *after* it 
though, which sucks).


But what you want to do is to read whitespace too. I think 
putting a space in the format string at the beginning or end will 
do it (I don't use readf often though).
