tests: avoid case-folding issue in test-evolve-inmemory.t on windows

When using debugdrawdag, each commit already creates a file with the same name
as the commit description, i.e. changeset C creates file C with 'C' in it (no
newline). Creating another file called c breaks this test on windows. So let's
reuse the files already created by debugdrawdag.

hg update reports one less file because now there's only C in C (yes, I also
wanted to change commit descriptions, file names and their contents to be less
ambiguous, but decided to be lazy).

=========================================
Testing single head enforcement: Case B-1
=========================================

A repository is set to only accept a single head per name (typically named
branch). However, obsolete changesets can make this enforcement more
complicated, because they can be kept visible by other changeset on other
branch.

This case is part of a series of tests checking this behavior.

Category B: Involving obsolescence with topic
TestCase 1: A fully obsolete topic kept visible by another one.

.. old-state:
..
.. * 2 changesets on topic X
.. * 2 changesets on topic Y on top of them.
..
.. new-state:
..
.. * 2 changesets on topic Y at the same location
.. * 2 changesets on topic X superseding the other ones
..
.. expected-result:
..
.. * only one head detected
..

Test setup
----------

  $ mkdir B1
  $ cd B1
  $ setuprepos single-head
  creating basic server and client repo
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd client
  $ hg topic -r . topic-X
  switching to topic topic-X
  changed topic on 1 changesets to "topic-X"
  $ hg strip --config extensions.strip= --hidden 'hidden()' --no-backup # clean old A0
  $ mkcommit B0
  $ hg topic topic-Y
  $ mkcommit C0
  active topic 'topic-Y' grew its first changeset
  (see 'hg help topics' for more information)
  $ mkcommit D0
  $ hg push --new-branch
  pushing to $TESTTMP/B1/server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 4 changesets with 3 changes to 4 files (+1 heads)
  1 new obsolescence markers
  obsoleted 1 changesets
  $ hg up 0
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ hg topic topic-X
  marked working directory as topic: topic-X
  $ mkcommit A1
