Typo in a documentation example

[henrik@…]

At ​Forms DateField documentation
in the second example box of input_formats the first line goes:

'%b %m %d',       # 'Oct 25 2006'

This should be either

'%b %m %d',       # 'Oct 25 06'

or

'%b %m %Y',       # 'Oct 25 2006'

Also under these examples would be beneficial to add link where the list of date modifiers could be found
