Introduction to history deltas

[John Yates]

As I understand it the text deltas are delta between clear text
versions of files, not between weaves.  Does this not preclude
using some of the more powerful merge algorithms?

Could not the text delta be redefined to express how to construct
a new weave from an earlier weave?  If that were the case, and if
the deltas are appropriately ordered then there must exist a one-
pass algorithm that both reconstructs the desired weave and also
produces one of the revisions encoded within the weave.
