here's what I can do, since I will grant that "rm" is inconvenient in that you 
have to type the path to the file:

alembic rm <revision>

will delete revision files, including a range like "alembic rm 5ea:head"

it must include an "are you sure?" dialog after it emits the pathnames of the 
files it will delete.
