Bug 2813: pass args separately instead of as list
Bug 2813: pass args separately instead of as list

When I switched to using optparse, I accidentally dropped the * for
the case where the command was a string instead of a function, which
is used in flushctl instead of elsewhere. This caused the arguments to
get passed as a single list instead of separately.
