Bugfix: index subscription out of range

Hi,
I accidentally introduced a bug, which can produce an index subscription out
of range assert in std::vector
Suppose you have 3 files:
   * file base.txt with single line.
   * file mine.txt with line from base.txt and one extra line
   * file theirs.txt with line from base.txt and at least 2 extra lines,
different from one extra in mine.txt
Three way diff will try to get a line ending at index, greater or equal to
line count in a base file.
So simple fix is in attached patch. Excuse me for this.
