Machine filter for reset-to-actual doesn't work

[markkent]

The help for reset-to-actual indicates that a machine filter is supported with a -m option:

SYNOPSIS
galaxy [--batch] [(-e | --environment )]
[--debug] reset-to-actual [--all] [(-u | --uuid )...]
[(-m | --machine )...]
[(-s | --state )...]
[(-c | --config )...] [(-h | --host )...]
[(-b | --binary )...]

However, the filter doesn't appear to work:

A filter is required
