Exceptions may be used for errors, but they're actually intended for
_exceptions_ to normal operation.

Normal operation for a function named "readline" is to return the next
char in the file and advance the file pointer.  There are two exceptions
to this behavior: when the file pointer is invalid, and when it can't be
advanced.  Both should be handled by exception, not by returning a special
value.
