minimal XML file with all commodities included

Hello,

when saving an XML file from GnuCash 2.5.8 (the same was not observed with 2.4.10), the resulting XML file includes "<commodity>" blocks for all possible currencies, each providing only the "user_symbol" slot.

This seems not to be by design, because the commodity count at the start of book is still equal to 1 ('<gnc:count-data cd:type="commodity">1</gnc:count-data>').

This is suboptimal because:
- the commodity count is not consistent with the data
- those many unused commodities lengthen and complicate the file for no good reason, and might break scripts which worked with 2.4 (I know these are weak reasons)
- the file now includes non-ASCII characters, which might break misconfigured systems (you know, like the one at your prefered tax office...)

Cheers,

Baptiste
