[office-formula] Case Sensitivity of Base Conversions

The spec says for the hex base a leading 0x and/or a trailing H are legal.  Are the x and H in that case-insensitive like the rest of the number?  What about pre-fixes and post-fixes for octal or binary?  Is there some generalization that applies to all bases? 


I've created Office-2321 to track this.
