This happens when you tag --user onto the end too: (and it seems to end up in
the replica config file rather than the user config file):
SD> alias reassign = ticket update $1 -- milestone $2
SD> alias
Active aliases for the current repository (including user-wide and global
aliases if not overridden):
tl = ticket list
ts = ticket show $1
nt = new ticket
reassign = ticket update $1
td = ticket details $1
cavil = ticket list -- milestone=cavil status=~new|open
mine = ticket list -- owner=~spang status!~closed|rejected
det = ticket details $1
