From reading the on-line docs, I think the examples below are proper behavior.  
Do you agree?

strsplit ("road to hell", " ^", "delimitertype", "simple")
ans = 
{
  [1,1] = road
  [1,2] = to
  [1,3] = hell
}
strsplit ("road to hell", " ^", "delimitertype", "regexp")
ans = 
{
  [1,1] = road to hell
}
strsplit ("road to hell", "[ ^]", "delimitertype", "regexp")
ans = 
{
  [1,1] = road
  [1,2] = to
  [1,3] = hell
}
