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 repo
  $ cd repo
  $ echo foo > foo
  $ chmod 644 foo
  $ hg ci -qAm '644'

  $ chmod 755 foo
  $ hg ci -qAm '755'

reverting to rev 0

  $ hg revert -a -r 0
  reverting foo
  $ hg st
  M foo
  $ hg diff --git
  diff --git a/foo b/foo
  old mode 100755
  new mode 100644

  $ cd ..
