hooks: back 9f272bf3b342 out

Changeset 9f272bf3b342 alters the 'HG_PENDING' mechanism to be "always" there.
This change is made under the assumption than we previously did it only when
"writepending() actually wrote something". This assumption was wrong,
'writepending()' informs of pending changes the first time something is written
and for all following calls. We back this change out to restore the former
behavior, which was already correct.
