New methods to handle VARCHAR strings and CHAR's which are not
using a binary collation.
Indentation fixes
Now strings are run through strnxfrm before they are processed
by the partition function
We do not allow collations where strnxfrm expands the string since
we want the resulting string to fit in the same value range as
the original.
