[PATCH] fix conflict stats for externals during update

Hi,

conflict stats don't seem to be printed for externals during update.

Running the attached script gives this output at the end:

  + svn up --accept=postpone conflict-stats-externals/trunk2
  C conflict-stats-externals/trunk2/alpha
  
  Fetching external item into 'conflict-stats-externals/trunk2/ext'
  C conflict-stats-externals/trunk2/ext/zeta
  Updated external to revision 5.
  
  Updated to revision 5.
  Summary of conflicts:
    Text conflicts: 1
  + svn st conflict-stats-externals/trunk2
  X conflict-stats-externals/trunk2/ext
  C conflict-stats-externals/trunk2/alpha
  ? conflict-stats-externals/trunk2/alpha.r3
  ? conflict-stats-externals/trunk2/alpha.r5
  ? conflict-stats-externals/trunk2/alpha.mine
  
  Performing status on external item at 'conflict-stats-externals/trunk2/ext'
  C /tmp/conflict-stats-externals/trunk2/ext/zeta
  ? /tmp/conflict-stats-externals/trunk2/ext/zeta.r3
  ? /tmp/conflict-stats-externals/trunk2/ext/zeta.r5
  ? /tmp/conflict-stats-externals/trunk2/ext/zeta.mine
  Summary of conflicts:
    Text conflicts: 2
  
Note how the update never prints a conflict count for the external,
and how its summary only accounts for conflicts which happened outside
the external.
I think the new 'svn status' summary does what we want -- it prints
the summary for the entire operation, including externals.

With the patch below, the update output changes to:

  + svn up --accept=postpone conflict-stats-externals/trunk2
  C conflict-stats-externals/trunk2/alpha
  
  Fetching external item into 'conflict-stats-externals/trunk2/ext'
  C conflict-stats-externals/trunk2/ext/zeta
  Updated external to revision 5.
  
  Updated to revision 5.
  Summary of conflicts:
    Text conflicts: 2

Any objections? Does anyone remember what the rationale was for
treating externals separately?

I haven't run this through make check yet.

Stefan
