[Interest] documentation for QString::right(int n) confuse

[Constantin Makshin]

If 'x' is equal to "Pineapple", then
x[0] = 'P'
x[1] = 'i'
x[2] = 'n'
x[3] = 'e'
x[4] = 'a'
x[5] = 'p'
x[6] = 'p'
x[7] = 'l'
x[8] = 'e'

No offence, but I don't understand how the phrase "n rightmost characters"
can be confusing to anyone. :-)
