Hi Stefan,

In case you missed it this was already discussed a little in this
thread: http://svn.haxx.se/dev/archive-2012-10/0102.shtml

I'm mostly open to whatever the majority of folks want to call these
properties. I personally favor names that are:

1) Parallel the config names and describe the basic purpose, i.e.
".*auto-props.*" and ".*ignores.*"
2) Are not impossibly long and unwieldy
3) Convey the fact that Subversion considers the property inheritable.

I suspect we are all in agreement in #1 and #2, it's #3 some don't
think necessary.

Re svn:mergeinfo, I think that's a unique case which has several
characteristics that don't necessarily set good precedents for generic
inheritable properties (e.g. can inherit from unreadable parent, only
inherits from nearest parent). If nothing else, since it predates the
inheritable property work, its naming scheme shouldn't hold much
influence over what we do going forward.
