More performance work would certainly be nice.

It'd be really nice to have custom file properties in - perhaps as part
of the inventory splitup ? Once custom file properties are supported, it
is possible to support a whole bunch of features through plugins without
requiring format bumps:

* line endings
* cherrypicking
* tracking svn properties
* tracking copies
* keyword expansion
* custom file-specific merging

Cheers,
