AFAIK pFormulaData (I assume you mean pFormulaData when you said
pFunctionData) is used only for formula tips during typing inside a
cell.  And it's not clear to me why we even populate pFormulaData from
pMRUList as it seems redundant and unnecessary.  One theory could be
that pFormulaData, which is now an associative container with O(log n)
lookup time, used to be an array container with O(n) lookup time and we
tried to put the most recent functions at the top.. (or something along
that line)  But I'm not sure 100%.

I for one would be okay with skipping this pMRUList.  I don't think we
need to do that anymore.

No idea about why we have MRU and LRU used interchangeably either.  But
I believe both refer to the "recently used function" list.
