             Bug #: 39766
           Summary: string.find only return only a number instead of an
                    array

string.find function only return a number instead of an array.

Some examples:
string.find("d'alfdf", "(al)") return 3 instead of {3, 4, "al"}
= string.find("d'alfdf", "^([a-d'])") return 1 instead of {1, 1, d}

Lua manual say :
string.find (s, pattern [, init [, plain]])
Looks for the first match of pattern in the string s. If it finds a match, then
find returns the indices of s where this occurrence starts and ends; otherwise,
it returns nil. [...]

If the pattern has captures, then in a successful match the captured values are
also returned, after the two indices.
