Str.string_before "f" 2 returns exception Invalid_argument.

However, according to the spec it should return "all chars that precede position
n".

In this case, the answer should be "f" since "f" are all chars that precede 2.

(In general, I think this is a general design flaw in the string-functions of
O'Caml, they should rarely return exception, just shorter strings. If
a programmer wants the behavior of string_before, he should check the
length himself. Strings are not arrays.

The current implementation makes it difficult just to check if a string
starts with "%%")
