revert: don't backup if no files reverted in interactive mode (issue4793)

When reverting interactively, we always backup files before prompting the user
to find out if they actually want to revert them. This can create spurious
*.orig files if a user enters an interactive revert session and then doesn't
revert any files. Instead, we should only backup files that are actually being
touched.

#require execbit

  $ hg init
  $ echo a > a
  $ hg ci -Am'not executable'
  adding a

  $ chmod +x a
  $ hg ci -m'executable'
  $ hg id

Make sure we notice the change of mode if the cached size == -1:

  $ hg rm a
  $ hg revert -r 0 a
  $ hg debugstate
  n   0         -1 unset               a
  $ hg status
  M a

  $ hg up 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg id
  d69afc33ff8a
  $ test -x a && echo executable -- bad || echo not executable -- good
  not executable -- good
