mergetools: vimdiff issue a warning explaining how to abort

Adds a message displayed at each vimdiff invocation:

  merge conflict detected, type ":cq" to abort

Vimdiff is very confusing for non-vim user (not to speak about vim user confused
anyway. However it is very likely that vimdiff is picked as the mergetool of
choice when using the default config:
- vim is available on all UNIX system.
- Its one of the rare non graphical merge tools.

  $ hg init

  $ echo a > a
  $ hg ci -qAm 'add a'

  $ hg init subrepo
  $ echo 'subrepo = http://example.net/libfoo' > .hgsub
  $ hg ci -qAm 'added subrepo'

  $ hg up -qC 0
  $ echo ax > a
  $ hg ci -m 'changed a'
  created new head

  $ hg up -qC 1
  $ cd subrepo
  $ echo b > b
  $ hg add b
  $ cd ..

Should fail, since there are added files to subrepo:

  $ hg merge
  abort: outstanding uncommitted changes in subrepository 'subrepo'
