[issue1259] string find and rfind methods give a TypeError that is misleading

Facundo Batista added the comment:
Documentation for find():
str.find(sub[, start[, end]])
Return the lowest index in the string where substring sub is found,
such that sub is contained in the range [start, end]. Optional arguments
start and end are interpreted as in slice notation. Return -1 if sub is
not found.
I think that it shouldn't be possible to call it with None arguments.
The error message is wrong: it's a TypeError, but the message should say
something like...
TypeError: slice indices must be integers or have an __index__ method
If you're ok with this change, assign this bug to me and I'll fix it.
