Change subject: Optimisation of method WordLevelDiff._split()
......................................................................
Optimisation of method WordLevelDiff._split()
_split() copied two arrays N times, where N is number of lines in diff.
This was done by $a = array_merge($a, ...);
Instead of doing this, new words are appended to the end of array
using []= syntax.
