diff: make sure we output stat even when --git is not passed (issue4037) (BC)

Before this patch, `hg diff --stat` will give an empty output. It will not show
the stat information. I debugged and found that the underlying code does not
return the diff header and due to that, other code paths fails to parse that as
a diff.

I looked into why we don't return diff headers in quiet mode and found the
behavior is from 8f8bb77d560e70bcc95577e4dfa877df18d876ab which does not have
any mention about why it is done. We also show the diff headers in git, so I
think it's fine showing diff header in normal diff in quiet mode.

Prepare parent repo
-------------------

  $ hg init r
  $ cd r

  $ echo a > a
  $ hg ci -Am0
  adding a

Link first subrepo
------------------

  $ echo 's = s' >> .hgsub
  $ hg add .hgsub
  $ hg init s

amend without .hgsub

  $ hg amend s
  abort: can't commit subrepos without .hgsub
  [255]

amend with subrepo

  $ hg amend
  saved backup bundle to * (glob) (obsstore-off !)
  $ hg status --change .
  A .hgsub
  A .hgsubstate
  A a
  $ cat .hgsubstate

Update subrepo
--------------

add new commit to be amended

  $ echo a >> a
  $ hg ci -m1

amend with dirty subrepo

  $ echo a >> s/a
  $ hg add -R s
  adding s/a
  $ hg amend
  abort: uncommitted changes in subrepository "s"
  (use --subrepos for recursive commit)
  [255]

amend with modified subrepo

  $ hg ci -R s -m0
  $ hg amend
  saved backup bundle to * (glob) (obsstore-off !)
  $ hg status --change .
  M .hgsubstate
  M a
  $ cat .hgsubstate

revert subrepo change

  $ hg up -R s -q null
  $ hg amend
  saved backup bundle to * (glob) (obsstore-off !)
  $ hg status --change .
  M a

Link another subrepo
--------------------

add new commit to be amended

  $ echo b >> b
  $ hg ci -qAm2

also checks if non-subrepo change is included

  $ echo a >> a

amend with another subrepo

  $ hg init t
  $ echo b >> t/b
  $ hg ci -R t -Am0
  adding b
  $ echo 't = t' >> .hgsub
  $ hg amend
  saved backup bundle to * (glob) (obsstore-off !)

Unlink one subrepo
------------------

add new commit to be amended

  $ echo a >> a
  $ hg ci -m3

amend with one subrepo dropped

  $ echo 't = t' > .hgsub
  $ hg amend
  saved backup bundle to * (glob) (obsstore-off !)
  $ hg status --change .
  M .hgsub
  M .hgsubstate
  M a
  $ cat .hgsubstate

Unlink subrepos completely
--------------------------

add new commit to be amended

  $ echo a >> a
  $ hg ci -m3

amend with .hgsub removed

  $ hg rm .hgsub
  $ hg amend
  saved backup bundle to * (glob) (obsstore-off !)
  $ hg status --change .
