line-log: fix "log -LN" crash when N is last line of file
range-set invariants are: ranges must be (1) non-empty, (2) disjoint,
(3) sorted in ascending order.
line_log_data_insert() breaks the non-empty invariant under the
following conditions: the incoming range is empty and the pathname
attached to the range has not yet been encountered. In this case,
line_log_data_insert() assigns the empty range to a new line_log_data
record without taking any action to ensure that the empty range is
eventually folded out. Subsequent range-set functions crash or throw an
assertion failure upon encountering such an anomaly. Fix this bug.
