15. 17. Dīghaṃ (36).

  Saro kho paro pubbasare lutte kvaci dīghaṃ pappoti.

When the previous vowel has been elided, the following vowel sometimes
becomes long.

Saddh' īdha vittaṃ purisassa seṭṭhaṃ (Khu. i, 306), anāgārehi c'
ūbhayaṃ (Khu. i, 71, 376).

Examples:
saddhīdha: saddhā idha; saddh ā idha (10); saddh idha (12); saddh īdha
(15); saddhīdha (11).
cūbhayaṃ: ca ubhayaṃ; c a ubhayaṃ (10); c ubhayaṃ (12); c ūbhayaṃ
(15); cūbhayaṃ (11).

Kvacī ti kasmā?  Pañcah' Upāli aṅgehi samannāgato (Vin. v, 342),
natth' aññaṃ kiñci.

Why say ‘sometimes'? To prevent the operation of this rule in the
following: Pañcah’ Upāli aṅgehi samannāgato, natth’ aññaṃ kiñci.

Counter Examples:
pañcahupāli: pañcahi upāli; pañcah i upāli (10); pañcah upāli (12);
pañcahupāli (11).
natthaññaṃ: natthi aññaṃ;  natth i aññaṃ (10);  natth aññaṃ (12);
natthaññaṃ (11)
