By convention, we indent the second and subsequent lines of descriptions and tagged sections, except for examples. Turn this into a hard rule, and apply it to examples, too.

# When there is no preceding snapshot or the execution is not

# replayed, then the command fails. icount for the reference may be

# obtained with @query-replay command.
