[Adam Spiers <adam@xxxxxxxxxxxxxxxxxxxxxxx>]

tweak to _other_accounts.

+This array is used for completion of usernames and hostnames for many

+item(var(command)tt(_accounts))(
+Any of the commands which use the above tt(my_accounts) and
+tt(other_accounts) arrays can have this behaviour overridden by
+specifying a username/hostname array unique to that command.
+For example, if you wanted tt(rcp) to complete usernames and hostnames
+from a different set of accounts, you could set the array
+tt(rcp_accounts) with username/hostname pairs in the same format as
+tt(my_accounts).
