route_data just provides the routing rules that would be found by
matching route_list, so what's valid syntax for a routing rule in either
is valid in the other.
Last paragraph of the introductory text in "20. THE MANUALROUTE ROUTER",
first paragraph in "20.4 Format of the list of hosts", which isn't quite
as clear as it might be since the relevant syntax is only described
above, rather than as being part of the general syntax.
Also, reading the source. Well, skimming.
manualroute_router_entry() (the entry point for handling the router at
all) first extracts from route_list or route_data before doing anything
else. The route_list case does not do any mangling of the data for
hosts_randomize. The local variable "randomize" is set to the copy of
the router option block's hosts_randomize variable, is changed by
presence of the routing options "randomize"/"no_randomize" and then
passed to host_build_hostlist() as the third parameter.
host.c:host_build_hostlist() then uses this generically.
