Comparisons using the +original source give lower estimates of untouched code, though either must be +viewed taking into account insignificant similarities (such as blank lines). + +Starting in 2.8.6dev.3, all C source code has been routinely indented using +the lnx-indent script from + https://invisible-island.net/cindent/ + +Current lynx releases contain a large amount of text other than C
