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

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.
