Hi,

I noticed a small bug in the way MediaWiki handles default arguments in
{{subst}}ituted templates - they don't get substituted at all. For example,
suppose you have a template containing the following:

    1={{{1}}} 2={{{2|default value}}}

Then, substituting the template like this

    {{template|foo}}

will result in

    1=foo 2={{{2|default value}}}

instead of the expected

    1=foo 2=default value

I'm pretty sure that this isn't the way template substitution is supposed to
work - and if it is, it's confusing as heck, which is a bug in itself as well. ;)

This happens both in 1.8.2 and 1.9alpha (r17974) (the current version running on
test.wikipedia.org), I've filed this as "trivial" since it's hardly more than an
annoyance that can easily be dealt with and since it doesn't actually affect the
rendered page, BTW.
