tests: remove some unnecessary config

Some of these tests were originally split from a single file that had (and
used) these options, and some of the tests were later created by just
mindlessly copypasting the same set of options that aren't applicable to the
newly written tests.

Things removed by this patch:

- web section from tests that don't use hg serve and don't push
- phases.publish from tests that don't exchange changesets between repos
- diff section from tests that don't have any diffs
- defaults section that sets the date

The defaults section that only adds -d '0 0' to commands should no longer be
necessary because run-tests.py sets devel.default-date='0 0' since 4.3, and all
command in evolve should respect this config option.

  Safely Rewriting History
  """"""""""""""""""""""""
  
      Obsolescence markers make it possible to mark changesets that have been
      deleted or superseded in a new version of the changeset.
  
      Unlike the previous way of handling such changes, by stripping the old
      changesets from the repository, obsolescence markers can be propagated
      between repositories. This allows for a safe and simple way of exchanging
      mutable history and altering it after the fact. Changeset phases are
      respected, such that only draft and secret changesets can be altered (see
      'hg help phases' for details).
  
      Obsolescence is tracked using "obsolete markers", a piece of metadata
      tracking which changesets have been made obsolete, potential successors
      for a given changeset, the moment the changeset was marked as obsolete,
      and the user who performed the rewriting operation. The markers are stored
      separately from standard changeset data can be exchanged without any of
      the precursor changesets, preventing unnecessary exchange of obsolescence
      data.
  
      The complete set of obsolescence markers describes a history of changeset
      modifications that is orthogonal to the repository history of file
      modifications. This changeset history allows for detection and automatic
      resolution of edge cases arising from multiple users rewriting the same
      part of history concurrently.
  
      Current feature status
      ======================
  
      This feature is still in development.  If you see this help, you have
      enabled an extension that turned this feature on.
  
      Obsolescence markers will be exchanged between repositories that
      explicitly assert support for the obsolescence feature (this can currently
      only be done via an extension).
  
      Instability
      ===========
  
      Rewriting changesets might introduce instability.
  
      There are two main kinds of instability: orphaning and diverging.
  
      Orphans are changesets left behind when their ancestors are rewritten.
      Divergence has two variants:
  
      * Content-divergence occurs when independent rewrites of the same
        changesets lead to different results.
      * Phase-divergence occurs when the old (obsolete) version of a changeset
        becomes public.
  
      It is possible to prevent local creation of orphans by using the following
      config:
  
        [experimental]
        evolution=createmarkers,allnewcommands,exchange
  
      You can also enable that option explicitly:
  
        [experimental]
        evolution=createmarkers,allnewcommands,allowunstable,exchange
  
      or simply:
  
        [experimental]
        evolution=all

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 (child of $(hg log -r . -T '{node|short}'))"

So here we are::

  $ hg book
     feature-A                 1:568a468b60fc
   * feature-B                 2:73296a82292a


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

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
  3	feature-B: another feature (child of 568a468b60fc) - 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

(amend of public changeset denied)

  $ hg phase --public 0 -v
  phase changed for 1 changesets


(amend of on ancestors)

  $ hg amend
  1 new orphan changesets
  $ hg log
