If I understand you correctly you want several places calling the un-escape
function (for auto-props, dir-auto-props, and authentication)?
That's possible, too, but I don't know which places all need that.

Well, there's not much I can do.
We need special characters for svn:ignore _and_ for the auth info
(http://marc.theaimsgroup.com/?l=subversion-dev&m=111175528516724&w=2), so
compatibility _has_ to give somewhere.

Although you're right - if we change the behaviour only for some parts, most
of the config file stays the same. But I don't believe that buys us anything
- if I understand you correctly, a single escape in the config file leads to
parsing problems with Python?
And in my feeling it's much worse to parse some parts of a file this way and
others that way - a standard way would be much better.

BTW: Python has good SVN bindings. Why not add this parser to the bindings, so
that a python module can ask "how would you parse this config file?"
This would make for a clean way in the future, as we'd have a clean API.
