If osis has a verse of the form:
<verse osisID="matt.1.1 matt.1.2">text of matt 1.1 and 1.2</verse>
then it shows up as:
Matt 1.1 text of matt 1.1 and 1.2
Matt 1.2 text of matt 1.1 and 1.2
This is because the index properly points both 1.1 and 1.2 to the start of the "compound" verse when the second verse is gotten then it is not noticed that it had already been gotten.
