290283fe69 Enable prefix-search in query-parsing and snippet generation. If the 
character immediately after the end of a term is '*', that term is
marked for prefix matching.  Modify term comparison in
snippetOffsetsOfColumn() to respect isPrefix.  fts2n.test runs prefix
searching through some obvious test cases. (CVS 3893)

using docListMerge(). (CVS 3891)

0b6212090f Propagate prefix flag through implementation of doclist query code. 
Also implement correct prefix-handling for traversal of interior nodes
of segment tree.  A given prefix can span multiple children of an
interior node, and from there the branches need to be followed in
parallel. (CVS 3889)

f055154108 Lift docListMerge() call out of loadSegmentLeavesInt() for prefix 
search.  Doclists from multiple prefix matches will need a union merge
function, which will have to logically happen across a segment before
doclists are merged between segments. (CVS 3887)

8ffcadb57e Break interior-node and leaf-node readers apart in loadSegment(). 
Previously, the code looped until the block was a leaf node as
indicated by a leading NUL.  Now the code loops until it finds a block
in the range of leaf nodes for this segment, then reads it using
LeavesReader.  This will make it easier to traverse a range of leaves
when doing a prefix search. (CVS 3884)

1c7ebb0805 Refactor fts2 loadSegmentLeaf() in preparation for prefix-searching. 
Prefix-searching will want to accumulate data across multiple leaves
in the segment, using LeavesReader instead of LeafReader is the first
step in that direction. (CVS 3881)
