[PATCH 0/5] range-set and line-log bug fixes

While implementing multiple -L support for git-blame, I encountered
several bugs in range-set and line-log resulting in crashes. This
series fixes those bugs.

Eric Sunshine (5):
  range-set: fix sort_and_merge_range_set() corner case bug
  t4211: demonstrate empty -L range crash
  range-set: satisfy non-empty ranges invariant
  t4211: demonstrate crash when first -L encountered is empty range
  line-log: fix "log -LN" crash when N is last line of file
