No way to format percentages including decimals in nl locale

[Wichert Akkerman]

In the nl locale percentages are always formatted without decimals:

>>> locale.numbers.getFormatter("percent").format(50.1)
'50%'

For most other things a locale can format you can use a 'long' length to get more information. No such luck here though:

>>> locale.numbers.getFormatter("percent", length="long").format(50.1)
KeyError: ('long',)
