Following an incr-merge operation that does not completely consume its input segments, store context in the rowid==1 row of the %_stat table that allows the next incr-merge to pick up where the previous left off. check-in: ab0a4f44 user: dan tags: fts4-incr-merge

# Test cases 5.*
#
# Test that if a crisis-merge occurs that disrupts an ongoing incremental
# merge, the next call to "merge=A,B" identifies this and starts a new
# incremental merge. There are two scenarios:
#
#   * There are less segments on the input level that the disrupted
#     incremental merge operated on, or
#   
#   * Sufficient segments exist on the input level but the segments 
#     contain keys smaller than the largest key in the potential output 
#     segment.
