Hi,

the documentation of the decimal module contains a small recipe called moneyfmt() for format decimal values. It's very usefull.

I'd like to suggest a small improvement because the output is incorrect with given dp="." (default) and places=0.

Example:
>>> moneyfmt(decimal.Decimal('-0.02'), neg='<', trailneg='>', places=1)
'<0.0>'
>>> moneyfmt(decimal.Decimal('-0.02'), neg='<', trailneg='>', places=0)
'<0.>'

Change:

+    if places:
+        build(dp)
     if not digits:
         build('0')
     i = 0

What do you think about the change?
