 Test --base for grafting the merge of 4 from the perspective of 5, thus only getting the change to d
 
   $ hg up -cqr 3
   $ hg graft -r 6 --base 5
   grafting 6:25a2b029d3ae "6" (tip)
   merging e
   $ hg st --change .
   M d
 
   $ hg -q strip . --config extensions.strip=
 
 Test --base for collapsing changesets 2 and 3, thus getting both b and c
 
   $ hg up -cqr 0
   $ hg graft -r 3 --base 1
   grafting 3:4c60f11aa304 "3"
   merging a and b to b
   merging a and c to c
   $ hg st --change .

 Specifying child as --base revision fails safely (perhaps slightly confusing, but consistent)
 
   $ hg graft -r 2 --base 3
   grafting 2:5c095ad7e90f "2"
   note: graft of 2:5c095ad7e90f created no changes to commit

 Need to specify a rev:
 
   $ hg graft

   [255]
 
 Can't graft ancestor:

 Graft from behind a move or rename
 ==================================
 
 NOTE: This is affected by issue5343, and will need updating when it's fixed
 
-Possible cases during a regular graft (when ca is between cta and c2):
+Consider this topology for a regular graft:
+
+o c1
+|
+| o c2
+| |
+| o ca # stands for "common ancestor"
+|/
+o cta # stands for "common topological ancestor"
+
+Note that in issue5343, ca==cta.
+
+The following table shows the possible cases. Here, "x->y" and, equivalently,
+"y<-x", where x is an ancestor of y, means that some copy happened from x to y.
 
 name | c1<-cta | cta<->ca | ca->c2
 A.0  |         |          |
 A.1  |    X    |          |
 A.2  |         |     X    |
 A.3  |         |          |   X
 A.4  |    X    |     X    |
 A.5  |    X    |          |   X
 A.6  |         |     X    |   X
 A.7  |    X    |     X    |   X
 
 A.0 is trivial, and doesn't need copy tracking.
 For A.1, a forward rename is recorded in the c1 pass, to be followed later.
 In A.2, the rename is recorded in the c2 pass and followed backwards.
 A.3 is recorded in the c2 pass as a forward rename to be duplicated on target.
 In A.4, both passes of checkcopies record incomplete renames, which are
 then joined in mergecopies to record a rename to be followed.
 In A.5 and A.7, the c1 pass records an incomplete rename, while the c2 pass
 records an incomplete divergence. The incomplete rename is then joined to the
 appropriate side of the incomplete divergence, and the result is recorded as a
 divergence. The code doesn't distinguish at all between these two cases, since
 the end result of them is the same: an incomplete divergence joined with an
 incomplete rename into a divergence.
 Finally, A.6 records a divergence entirely in the c2 pass.
 
 A.4 has a degenerate case a<-b<-a->a, where checkcopies isn't needed at all.
 A.5 has a special case a<-b<-b->a, which is treated like a<-b->a in a merge.
+A.5 has issue5343 as a special case.
+TODO: add test coverage for A.5
 A.6 has a special case a<-a<-b->a. Here, checkcopies will find a spurious
 incomplete divergence, which is in fact complete. This is handled later in
 mergecopies.
 A.7 has 4 special cases: a<-b<-a->b (the "ping-pong" case), a<-b<-c->b,
 a<-b<-a->c and a<-b<-c->a. Of these, only the "ping-pong" case is interesting,
 the others are fairly trivial (a<-b<-c->b and a<-b<-a->c proceed like the base
 case, a<-b<-c->a is treated the same as a<-b<-b->a).
 
 f5a therefore tests the "ping-pong" rename case, where a file is renamed to the
 same name on both branches, then the rename is backed out on one branch, and
 the backout is grafted to the other branch. This creates a challenging rename
 sequence of a<-b<-a->b in the graft target, topological CA, graft CA and graft
 source, respectively. Since rename detection will run on the c1 side for such a
 sequence (as for technical reasons, we split the c1 and c2 sides not at the
 graft CA, but rather at the topological CA), it will pick up a false rename,
 and cause a spurious merge conflict. This false rename is always exactly the
 reverse of the true rename that would be detected on the c2 side, so we can
 correct for it by detecting this condition and reversing as necessary.
 
 First, set up the repository with commits to be grafted

 Grafting of plain changes correctly detects that 3 and 5 should be skipped:
 
   $ hg up -qCr 4
   $ hg graft --tool :local -r 2::5
   skipping already grafted revision 3:ca093ca2f1d9 (was grafted from 1:13ec5badbf2a)
   skipping already grafted revision 5:43e9eb70dab0 (was grafted from 4:6c9a1289e5f1)
   grafting 2:42127f193bcd "b"
 
 Extending the graft range to include a (skipped) merge of 3 will not prevent us from
 also detecting that both 3 and 5 should be skipped:
 
   $ hg up -qCr 4
   $ hg graft --tool :local -r 2::7
   skipping ungraftable merge revision 6
   skipping already grafted revision 3:ca093ca2f1d9 (was grafted from 1:13ec5badbf2a)
