Description:
A typo in Item_func_export_set::fix_length_and_dec() caused the function to require all arguments to have identical collations.

How to repeat:
select export_set(3, _latin1'foo', _utf8'bar', ',', 4);

Suggested fix:
Put MY_COLL_ALLOW_CONV inside the agg_arg_charsets() function, not outside it.

Remove the default value for the flags argument of agg_arg_charsets() while we're at it.

Note: this bug is only in 4.1; 5.0+ don't have it (or have already been fixed).
