fold: require --from flag for folding revisions to working copy It's very easy to think that "hg fold 4::6" will fold exactly those revisions. In reality, it will fold those *and* any revisions between them and the working copy. To prevent users from making that mistake, require the use of a new --from flag for folding revisions from the given set to the working copy. With this change, I'm sure some users will be surprised that the command can not be run without either --from or --exact, but at least the consequences will be smaller (the command simply aborts and the user can try again).

-----------------------------------------
Good practice for (early) users of evolve
-----------------------------------------

Avoid unstability
-----------------

The less unstability you have the less you need to resolve.

Evolve is not yet able to detect and solve every situation. And your mind is
not ready neither.

Branch as much as possible
--------------------------

This is not MQ; you are not constrained to linear history.

Making a branch per independent branch will help you avoid unstability
and conflict.

Rewrite your changes only
-------------------------

There is no descent conflict detection and handling right now.
Rewriting other people's changesets guarantees that you will get
conflicts. Communicate with your fellow developers before trying to
touch other people's work (which is a good practice in any case).

Using multiple branches will help you to achieve this goal.

Prefer pushing unstability to touching other people changesets
--------------------------------------------------------------


If you have children changesets from other people that you don't really care
about, prefer not altering them to risking a conflict by stabilizing them.


Do not get too confident
------------------------

This is an experimental extension and a complex concept. This is beautiful,
powerful and robust on paper, but the tool and your mind may not be prepared for
all situations yet.
