Getting chunks from Codemirror.

[nakul-py]

Using chunks provided by Codemirror acceptChunk, rejectChunk instead of handling them manually.

This seems to add more complexity.
I wonder if there is an advantage of accepting/rejecting chunks one by one when we want to update the whole file.

That's a fair point. Since accept/reject applies to the whole document, we don’t strictly need chunk-level operations.
The reason I used chunks here just was to align with the CodeMirror merge extension.

However, I agree that if we only support full-document accept/reject here, the simpler approach may be preferable.
