copies: delete debug message about search limit

I'm about to rewrite mergecopies() and this message will no longer be
emitted then. Let's remove the message now to remove a distraction
from that patch.

 Graft from behind a move or rename
 ==================================
 
 NOTE: This is affected by issue5343, and will need updating when it's fixed
 
 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.
 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

 two renames actually converge to the same name (thus no actual divergence).

 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)
   skipping already grafted revision 5:43e9eb70dab0 (was grafted from 4:6c9a1289e5f1)

 In the merge below, the file "foo" has the same contents in both
 parents, but if we look at the file-level history, we'll notice that
 the version in p1 is an ancestor of the version in p2. This test makes
 sure that we'll use the version from p2 in the manifest of the merge

 Test behavior of add for explicit path in subrepo:
   $ cd ..
   $ hg init explicit
   $ cd explicit
   $ echo s = s > .hgsub
   $ hg add .hgsub
   $ hg init s
   $ hg ci -m0
 Adding with an explicit path in a subrepo adds the file
   $ echo c1 > f1
   $ echo c2 > s/f2
   $ hg st -S
   ? f1
   ? s/f2
   $ hg add s/f2
   $ hg st -S
   A s/f2
   ? f1
   $ hg ci -R s -m0
   $ hg ci -Am1
   adding f1
 Adding with an explicit path in a subrepo with -S has the same behavior
   $ echo c3 > f3
   $ echo c4 > s/f4
   $ hg st -S
   ? f3
   ? s/f4
   $ hg add -S s/f4
   $ hg st -S

 Adding without a path or pattern silently ignores subrepos

   $ hg ci -R s -Am2

 Adding without a path or pattern with -S also adds files in subrepos
   $ echo c8 > f8

   $ hg ci -R s -Am4

   $ echo c18 > s/fn18
   $ hg st -S

 Test behavior of forget for explicit path in subrepo:
 Forgetting an explicit path in a subrepo untracks the file
   $ echo c19 > s/f19

   $ hg forget s/f19

   $ hg convert --config extensions.convert= -q t/s/ss tconv/s/ss
   $ hg convert --config extensions.convert= -q t/t tconv/t
 
  convert shouldn't fail because of pseudo filenode:
