I don't want to attempt to pollute Django's beautiful template library
namespace with garbage, but I do see a legitimate value for a
linebreaksli template filter.  It does just what it says - converts a
string with linebreaks into a set of list items.  Sometimes, a <p> tag
just doesn't do the same thing, especially if you want to number the
items with an <ol>.  My code is below.  It wouldn't take too much to
convert it to a Django template filter.  What does everyone think?

def linebreaksli(value):
        "Converts strings with newlines into <li></li>s"
        value = re.sub(r'\r\n|\r|\n', '\n', value) # normalize newlines
        lines = re.split('\n', value)
        lines = ['<li>%s</li>' % line for line in lines]
        return '\n'.join(lines)
