Summary
~~~~~~~

Beginning with Curator v3, `--prefix` is interpreted as part of a regular
expression pattern. This means that if you specify `--prefix l`, it will match
indices or snapshots named, __logstash__, __local__, __l-2015.03.05__, or
anything that begins with the letter __l__. The <<suffix>> flag exhibits similar
behavior, but with the pattern matching the end of the line instead.
