branchcache: do not accept "empty update"

This currently does not happens and it will be simpler that is remains that way.
If all update do something, we will be able to simply declare, in a later
changesets, that all update to result in a dirty branchcache.

  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > absorb=
  > EOF

  $ hg init repo1
  $ cd repo1

Make some commits:

  $ for i in 1 2 3; do
  >   echo $i >> a
  >   hg commit -A a -m "commit $i" -q
  > done

absorb --edit-lines will run the editor if filename is provided:

  $ hg absorb --edit-lines
  nothing applied
  [1]
  $ HGEDITOR=cat hg absorb --edit-lines a
  HG: editing a
  HG: "y" means the line to the right exists in the changeset to the top
  HG:
  HG: /---- 4ec16f85269a commit 1
  HG: |/--- 5c5f95224a50 commit 2
  HG: ||/-- 43f0a75bede7 commit 3
  HG: |||
      yyy : 1
       yy : 2
        y : 3
  nothing applied
  [1]

Edit the file using --edit-lines:

  $ cat > editortext << EOF
  >       y : a
  >      yy :  b
  >      y  : c
  >     yy  : d  
  >     y y : e
  >     y   : f
  >     yyy : g
  > EOF
  $ HGEDITOR='cat editortext >' hg absorb -q --edit-lines a
  $ hg cat -r 0 a
  d

  $ hg cat -r 1 a

  $ hg cat -r 2 a
