Fixed condition of `\}' closing a conditional at the start of the line.

Fixed flushed-out condition of \} causing subsequent arguments to be
truncated, when in fact the whole line should be passed through (if the
conditional succeeds) to the front-end and the \} ignored there.

Added regression test of this behaviour.
