rebase: in --confirm option just abort if hit a conflict

Before this patch, it was prompting the user in both cases 1) when
there is no conflict 2) when there is at least one conflict. But
for simplicity we can just abort if we hit a conflict and no need to
prompt in that case.

Rebase a simple DAG:
  $ hg init repo1
  $ cd repo1
  $ hg debugdrawdag <<'EOS'
  > c b
  > |/
  > d
  > |
  > a
  > EOS
  $ hg up -C a
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg tglog
  o  3: 814f6bd05178 'c'

  | o  2: db0e82a16a62 'b'
  |/
  o  1: 02952614a83d 'd'
  |
  @  0: b173517d0057 'a'
  
  $ hg cat -r 3 c
  c (no-eol)
  $ hg cat -r 2 b
  b (no-eol)
  $ hg rebase --debug -r b -d c | grep rebasing
  rebasing in-memory
  rebasing 2:db0e82a16a62 "b" (b)
  $ hg tglog
  o  3: ca58782ad1e4 'b'
  |
  o  2: 814f6bd05178 'c'
  |
  o  1: 02952614a83d 'd'
  |
  @  0: b173517d0057 'a'
  
  $ hg cat -r 3 b
  b (no-eol)
  $ hg cat -r 2 c
  c (no-eol)

Case 2:
  $ hg init repo2
  $ cd repo2
  $ hg debugdrawdag <<'EOS'
  > c b
  > |/
  > d
  > |
  > a
  > EOS

Add a symlink and executable file:
  $ hg up -C c
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ ln -s somefile e
  $ echo f > f
  $ chmod +x f
  $ hg add e f
  $ hg amend -q
  $ hg up -Cq a

Write files to the working copy, and ensure they're still there after the rebase
  $ echo "abc" > a
  $ ln -s def b
  $ echo "ghi" > c
  $ echo "jkl" > d
  $ echo "mno" > e
  $ hg tglog

Ensure working copy files are still there:
  $ cat a
  abc
  $ readlink.py b
  b -> def
  $ cat e
  mno

Ensure symlink and executable files were rebased properly:
  $ hg up -Cq 3
  $ readlink.py e
  e -> somefile
  $ ls -l f | cut -c -10
  -rwxr-xr-x

Rebase the working copy parent
  $ hg up -C 3
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg rebase -r 3 -d 0 --debug | grep rebasing
  rebasing in-memory
