tests: demonstrate broken manifest generation with the pure module

This will be fixed next.  But I don't fully understand how 'b.txt' is actually
removed properly in the second test, given what's broken.  Also, I'm not sure
why 'bb.txt' is flagged as not being in the manifest, when it clearly appears
to be.

Test file removal (especially with pure).  The tests are crafted such that there
will be contiguous spans of existing entries to ensure that is handled properly.
(In this case, a.txt, aa.txt and c.txt, cc.txt, and ccc.txt)

  $ cat > $TESTTMP/manifest.py <<EOF
  > from mercurial import (
  >     extensions,
  >     manifest,

  > def extsetup(ui):
  >     manifest.FASTDELTA_TEXTDIFF_THRESHOLD = 0
  > EOF
  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > manifest = $TESTTMP/manifest.py
  > EOF

BROKEN: Pure removes should actually remove all dropped entries
