It would be nice to have the --unified switch in darcs changes, to get more
context when looking at the history.

However this could be too much time consuming.

As a work around, I've copied the whole repo, obliterated up to the change,
unrecorded that change, and called darcs whatsnew.

Would darcs diff --from-patch --to-patch have helped here?

There is also darcs changes --count and darc sdiff --index N-M

Indeed, this is far better.

Don't really works for me

$ darcs diff --index 1-2
darcs failed:  Pattern not specified in get_first_match.

Do we still need this feature, in your opinion?

Could you submit a new bug report for this?

No "darcs diff" is fine, however it was not obvious to me that
if "darcs changes" cannot do it then "darcs diff" could.
That's maybe a documentation issue.

Done (1378).

Thanks, marking wont-fix.
Feel free to open a new bug (or better yet send a patch) if you think the user
manual could stand to talk more about the relationship between changes and diff.
