Change compactitemize to also use triangles
Someday I wanted to use both a regular
itemize enrivonment as well as a
compactitemize environment for space reasons, but discovered that they are differently represented (the former uses triangles to the right, while the latter uses bullets).
For the other types of environments (
enumerate) both the compactified and the original version use the same symbol. Are there any deeper reasons for the bullet symbol? Otherwise, I suggest to change it to the right-directed triangle for consistency.
