concat default template filter

[Alex Hayes]

It would be really nice to be able to concat variables or strings together within a template so that the concat'd values can be then sent into another filter. This can be done using stringformat however its not exactly that pretty and possibly prone to problems. For example:

?next={{ object.get_absolute_url|stringformat:'s#add-comment'|urlencode }}

The included patch for the file source:django/trunk/django/template/defaultfilters.py allows the following to be performed:

?next={{ object.get_absolute_url|concat:'#add-comment'|urlencode }}

I am sure that I would not be the first person to have this problem, so if there is a better solution I would be happy to hear it.
