libstdc++/5708: Problems with money_put

[Paolo Carlini]

Ok, correction, sorry. Upon discussion on the libstdc++ we now agree that in
fact the correct output is:

val: -123456 fmt: *(1,234.56)
lval: -123456 fmt: *(1,234.56)

That is the space is required and the fill char '*' must be used for it.
(once again, however, correctly no symbol must be output since showbase is false
by default).
