merge: delay prompts a bit and show them in (extra) sorted order

Preparing for backout of 760c0d67ce5e.

The number of prompts will for all relevant cases be significantly smaller than
the total number of files in the manifests. We can thus afford to sort the
prompts more than we can afford to sort the manifests.

  $ hg init foo
  $ cd foo

mq may keep a reference to the repository so __del__ will not be
called and .hg/journal.dirstate will not be deleted:

  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]
  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]

  $ cd ..
