branch: add tests which shows branch can be closed from a non-branchhead cset

This patch shows that we can close a branch even from a cset which is not
a branch head. It was supposed to abort this operation.
Next patch will be fixing the issue.

check whether HG_PENDING makes pending changes only in relatd
repositories visible to an external hook.

In "hg share" case, another transaction can't run in other
repositories sharing same source repository, because starting
transaction requires locking store of source repository.

Therefore, this test scenario ignores checking visibility of
.hg/bookmakrs.pending in repo2, which shares repo1 without bookmarks.

  $ cat > $TESTTMP/checkbookmarks.sh <<EOF
  > echo "@repo1"
  > hg -R "$TESTTMP/repo1" bookmarks
  > echo "@repo2"
  > hg -R "$TESTTMP/repo2" bookmarks
  > echo "@repo3"
  > hg -R "$TESTTMP/repo3" bookmarks
  > exit 1 # to avoid adding new bookmark for subsequent tests
  > EOF

FYI, in contrast to above test, bmX is invisible in repo1 (= shared
src), because (1) HG_PENDING refers only repo3 and (2)
"bookmarks.pending" is written only into repo3.
