docs: add missing ids (follow-up/fix)

This commit partially replay some changes introduced with commit:
9bc6f4bb90e8f663af20a31e1370e645b9beb3f4
That commit was applied to the KDE/4.9 branch which was then merged
into master, but part of the changes have been hidden during the
merge, maybe because of a cherry-picked commit in master which
reverted some change on the same files.
