evovle: remove redundancy in evolve output
Copying the discription of this redundancy issue given by Pierre Yves David:
When running `hg evolve` to stabilize orphan changeset output about the
currently stabilized changeset is issued. For example:
$ hg evolve
move:[3] a3
atop:[4] a2
working directory is now at 7c5649f73d11
This output can become quite repetitive when orphan are stabilized atop
each other. For example:
$ hg evolve --all
move:[8] dansk 2!
atop:[10] dansk!
merging main-file-1
move:[9] dansk 3!
atop:[11] dansk 2!
In this case it would be smoother to issue:
$ hg evolve --all
move:[8] dansk 2!
atop:[10] dansk!
merging main-file-1
move:[9] dansk 3!
Since we are moving "dansk 3!" atop the changeset we just stabilized.
When adding this be careful that we still want to issue the "atop" message
in various cases:
1. first changesets in a stack
2. when the orphan is not stabilized atop previous one
3. when using hg evolve --continue to resume an evolution
So, I have made the changes which also respect above listed three points.
And changes in tests/test-evovle*.t reflecting the changed behavior.
This test file test the #5720 issue
Check that `hg evolve --continue` doesn't change changeset phase from secret
to draft after a merge conflict.

Global setup
============

$ cat >> $HGRCPATH <<EOF

Test
====
$ hg init $TESTTMP/issue-5720
$ cd $TESTTMP/issue-5720
Create two drafts commits and one secret
$ echo a > a
$ hg commit -Am a
adding a
$ echo b > a
$ hg commit -m b
$ echo c > a
$ hg commit --secret -m c
$ hg log -G -T "{rev}: {phase}"
@ 2: secret
|
o 1: draft
|
o 0: draft
Amend the second draft with new content
$ hg prev
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
[1] b
$ echo b2 > a
$ hg amend
1 new orphan changesets
$ hg log -G -T "{rev}: {phase}"
@ 3: draft
|
| * 2: secret
| |
| x 1: draft
|/
o 0: draft
Evolve which triggers a conflict
$ hg evolve
move:[2] c
atop:[3] b
merging a
warning: conflicts while merging a! (edit, then use 'hg resolve --mark')
fix conflicts and see `hg help evolve.interrupted`
[1]
Fix the conflict
$ echo c2 > a
$ hg resolve -m
(no more unresolved files)
continue: hg evolve --continue
Continue the evolution
$ hg evolve --continue
evolving 2:13833940840c "c"
working directory is now at 3d2080c198e5
Tip should stay in secret phase
$ hg log -G -T "{rev}: {phase}"
@ 4: secret
|
o 3: draft
|
o 0: draft
$ hg log -r . -T '{phase}\n'
secret
