The gaps are added to avoid a phrase (or NEAR) matching across the last
word(s) of one field and the first word(s) of the next.

It's a bug that scriptindex doesn't add them too, really.  I'll fix that
once I've finished the move from CVS to SVN.

Because it isn't important where positions start - only the relative
positions really matter.

Actually, you have the situation reversed.  It's omindex which starts
from 1, scriptindex from 0.
