fncache: document the fact fncache is outdate at hook run time

Using 'addfinalize' to generate 'fncache' means that no pending version of the
file will be generated for the hooks. We would have to use the
'addfilegenerator' method to get such result. However the 'fncachevfs' (who
decide that a write is necessary) have no access to the transaction to register
such file generation at add time. Having the transaction accessible to the 'vfs'
is too much trouble for no benefit. This outdated 'fncache' file at hook time is
not expected to be an issue.

The previous move from 'onclose' to 'addfinalize' had no impact on this timing.
I'm documenting it now because I looked at it.

#require execbit

b51a8138292a introduced a regression where we would mention in the
changelog executable files added by the second parent of a merge. Test
that that doesn't happen anymore

  $ hg init repo
  $ cd repo
  $ echo foo > foo
  $ hg ci -qAm 'add foo'

  $ echo bar > bar
  $ chmod +x bar
  $ hg ci -qAm 'add bar'

manifest of p2:

  $ hg manifest
  bar
  foo

  $ hg up -qC 0
  $ echo >> foo
  $ hg ci -m 'change foo'
  created new head

manifest of p1:

  $ hg manifest
  foo

  $ hg merge
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ chmod +x foo
  $ hg ci -m 'merge'

this should not mention bar but should mention foo:
