obsolete: do not obsolete rebase --detach nullmerge revs

Rebase state contains the changesets to rebase as well as 'nullmerge'
entries used drive the merge strategy. These nullmerge were not rebased
and should be ignored, and certainly not be marked obsolete.

Creating And Updating Changeset
===============================

Setup the Base Repo
-------------------

We start with a plain base repo::

  $ hg init main; cd main
  $ cat >main-file-1 <<-EOF
  > One
  > 
  > Two
  > 
  > Three
  > EOF
  $ echo Two >main-file-2
  $ hg add
  adding main-file-1
  adding main-file-2
  $ hg commit --message base
  $ cd ..

and clone this into a new repo where we do our work::

  $ hg clone main work
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd work


Create First Patch
------------------

To begin with, we just do the changes that will be the initial version of the changeset::

  $ echo One >file-from-A
  $ sed -i'' -e s/One/Eins/ main-file-1
  $ hg add file-from-A

So this is what we would like our changeset to be::

  $ hg diff
  diff --git a/file-from-A b/file-from-A
  new file mode 100644
  --- /dev/null
  +++ b/file-from-A
  @@ -0,0 +1,1 @@
  +One
  diff --git a/main-file-1 b/main-file-1
  --- a/main-file-1
  +++ b/main-file-1
  @@ -1,1 +1,1 @@
  -One
  +Eins

To commit it we just - commit it::

  $ hg commit --message "a nifty feature"

and place a bookmark so we can easily refer to it again (which we could have done before the commit)::

  $ hg book feature-A


Create Second Patch
-------------------

Let's do this again for the second changeset::

  $ echo Two >file-from-B
  $ sed -i'' -e s/Two/Zwie/ main-file-1
  $ hg add file-from-B

Before committing, however, we need to switch to a new bookmark for the second
changeset. Otherwise we would inadvertently move the bookmark for our first changeset.
It is therefore advisable to always set the bookmark before committing::

  $ hg book feature-B
  $ hg commit --message "another feature"

So here we are::

  $ hg book
     feature-A                 1:568a468b60fc
   * feature-B                 2:7b36850622b2


Fix The Second Patch
--------------------

There's a typo in feature-B. We spelled *Zwie* instead of *Zwei*::

  $ hg diff --change tip | grep -F Zwie
  +Zwie

Fixing this is very easy. Just change::

  $ sed -i'' -e s/Zwie/Zwei/ main-file-1

and **amend**::

  $ hg amend --note "fix spelling of Zwei"

The `--note` is our commit message for the *update* only. So its only purpose
is to document the evolution of the changeset. If we use `--message` with
`amend`, it replaces the commit message of the changeset itself.

This results in a new single changeset for our amended changeset, and the old
changeset plus the updating changeset are hidden from view by default::

  $ hg log
  4	feature-B: another feature - test
  1	feature-A: a nifty feature - test
  0	: base - test

  $ hg up feature-A -q
  $ hg bookmark -i feature-A
  $ sed -i'' -e s/Eins/Un/ main-file-1

  $ hg amend --note 'french looks better'
  1 new unstables changesets
  $ hg log
  6	feature-A: a nifty feature - test
  4	feature-B: another feature - test
  1	: a nifty feature - test
  0	: base - test
  $ hg up -q 1
  Working directory parent is obsolete
  $ hg stabilize
  move:[4] another feature
  atop:[6] a nifty feature
  merging main-file-1
  $ hg log
  7	feature-B: another feature - test
  6	feature-A: a nifty feature - test
  0	: base - test

Test commit -o options

  $ hg up 6
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg revert -r 7 --all
  adding file-from-B
  reverting main-file-1
  $ sed -i'' -e s/Zwei/deux/ main-file-1
  $ hg commit -m 'another feature that rox' -o 7
  created new head
  $ hg log
  8	feature-B: another feature that rox - test
  6	feature-A: a nifty feature - test
  0	: base - test
  $ cd ..
