samba 4 smb.conf substitutions

[Amin Azez]

Are % substitutions going away in Samba 4 or is it something I can start
fixing now?

In loadparm.c:

#define standard_sub_basic talloc_strdup

means that lines like:

  include         = /usr/local/samba/etc/server-%i.conf

results in smbd complaining:
  Can't find include file /usr/local/samba/etc/server-%i.conf

Home directories seem to use string_sub_talloc and only %H is expanded

Whats the plans?
