 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.

 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.
