Re: [exim-dev] patch for named acl variables

This is already done, as named variables are identified by an underscore
after the c/m (e.g. acl_m_name1 in contrast to acl_m5). In the
consolidated code, this is not necessary any more.

Oh, are you sure about that? I think many people (including me) rely on
variables being empty by default. It's surely no big deal to set to the
empty string them at the beginning of the connect and mail acl. This
should probably be configurable (strict_var_names, like "use strict" in
perl).

I'll see when I can finish it. Would be good if others could also test it.

Have a nice vacation!
