svn 1.10: mod_authz no longer combines ACL entries

Hi,

we used up to and including svn 1.9 an authz file of the format

[groups]
company = user1, user2, user3
customer = customer1, customer2

# company can read-write on everything
[/]
@company = rw

[project1:/]
@customer = r

[project2:/]

This gave company full rights on both project1 and project2 and customer
reading rights on project1. Now, with svn 1.10, company cannot access
anything (customer can still read project 1). So apparently, only the ACLs
in the most specific matching block are used and parent ACLs not at all.

Even like this, within a single repository, this is the case:

[project1:/]
@company = rw

[project1:/trunk/src]
@customer = r

It results, that in trunk/src and below ONLY customer can read, company
has no rights.

Is this really an intentional change? It results in our case in a huge
amount of duplicated ACL entries and seems a rather drastic change
regarding backwards compatibility.

Best regards,
