Indeed, that's my question. Or:

Server specifies

    global-ignores = *.o ...

User happens to spread *.class files around in his working copy and
wants to "add":

    global-ignores = *.class

But, if at some point we might want to allow (well-behaved) clients to
override certain properties (if so allowed by the server), we might
need to make the distinction between "overriding" and "extending".
Maybe some special syntax would help, to indicate extension?

    *.c += svn:keywords=HeadURL

or

    *.c = ;svn:keywords=HeadURL

or something like that.

Oh, but what about "multi-valued" auto-props:

Server specifies:

    *.c = svn:keywords=Author Date

User wants to also add HeadURL as keyword:

    *.c += svn:keywords=HeadURL

Hm, that's really an edge case, probably not that interesting :-) ...
(and the problem is somewhat similar with the various ways of
specifying properties that exist today (command-line options, user
config file, system config file, ...))

Maybe "overriding" would also need a special syntax in the future, to
avoid back-compat problems with old config files still lying around:

    *.c == svn:keywords=HeadURL

or something like that ...
