Big, Middle, and Little Endians


Fixes rewrites for non-Big Endian date permastructs



Regardless of your post permastruct, date archives are generated.
Post rewrites completely clobber date rewrites. Date rewrites are broken already, but even when fixed,
they can be overwritten by post rewrites. This plugin fixes date archives and persists them past post overwrites –
supporting every possible flavor of endian, and every logical combination of %year%, %monthnum%, %day% within them.
Below is a matrix of what is possible, the things which do not work in core are marked.

Year and Month archives don’t work when you date format is Middle or Little Endian.
Year archives work in Middle when reversed (reversed, why not), but months do not.

This plugin makes all date formats work regardless of endianness.
