I had a thought that a nicer, platform-agnostic approach would be to  
have the plugin tweak the delta to ignore any exec bit changes.  But  
none of the hooks seem to allow changing the delta.  pre_commit seems  
the obvious candidate, but its docs say:

	tree_delta is a TreeDelta object describing changes from
	the basis revision. hooks MUST NOT modify this delta.
	future_tree is an in-memory tree obtained from
	CommitBuilder.revision_tree() and hooks MUST NOT
	modify this tree.

Is there a way to accomplish this type of change from a plugin?
