Rewrite is called at the very end, so it doesn't usually matter how you put it
together. args is treated somewhat differently from the function, in that it's
urllib.quote'd, but that won't make a difference here. If it did, you could
also write:
URL('admin', 'default', 'edit', args=[request.application, 'controllers',
'%s.py' % request.controller=='appadmin' and 'default' or
request.controller])
The effect would be the same, unless (as is not the case here) quoting args
made a difference.
Minor point: I don't think there's any need to escape the newline inside parens.
