[suheng] : thanks, However, your example just covers one condition. Can
you give me a basic conflict rule policy of SVN so I can conclude all
conditions?
  As your example, can I thought whenever a low revision(C) merge to a
high revision(when B merge to A, A will be A+1), a text conflict will be
pop up whatever the line is changed?
  In your example, the precondition is file a is revision A, then the
same file under change B is revision B = A + n(n>0), and same file under
change C is revision C = B + n(n>0), when change B is merged to A, we
must commit it firstly(at this time revision A will be rise to A+n > B
&& A+n > C, then do another merge I mean change C will be merged in A+n,
then conflict out.
  I think if C is a branch of from revision B+n(n>1) but not A, when we
merge C+n(n>1) won't involve conflict, right?

  Hmm...I think it has little confusing. you can ignore my explain, just
suggest me the basic conflict policy is appreciated.^_^
