I had to do some rcs file mangling recently, with thousands of revisions
of very large files. Using co directly was unacceptable because of the
O(N^2) nature.

Instead, I used a slightly modified rcsparse to extract not only the change
metadata, but the deltas themselves, and the fulltext of the HEAD.

I took HEAD and picked up the deltas in reverse order, reconstructing
all of the fulltexts in N passes (there were no branches in these
rcs files).

This gave me a tremendous speedup, but wouldn't it also allow us to
remove the requirement for "co"?
