Description

I'll explain on a simple example...

Let's say I have a template called Substing, it's source is:
{{#if:{{{1|}}}|{{{1}}}|7}}

Now let us have 3 situations:

{{subst:Substing}}
{{subst:Substing|}}
{{subst:Substing|3}}

This should give me:

So far it all works, but now let's say I want the template to be permanent (so
there will only be numbers in the source). Should be easy - changing the source to:
{{<includeonly>subst:</includeonly>#if:{{{1|}}}|{{{1}}}|7}}

And now let us have those 3 situations:

{{subst:Substing}}
{{subst:Substing|}}
{{subst:Substing|3}}

This should give me:

But it gives me:

{{{1}}}
7
3

So the first one is wrong.

I found a similar bug. Maybee it's the same. For example, I created a template called "Negative" which calculates something. The source of this template is {{<includeonly>subst:</includeonly>#expr: -{{{1}}} }} for example.

Usage: {{subst:Negative|7}}
Result: -7

Usage: {{Negative|7}}
Result: {{subst:#expr: -{{{1}}} }}

This is very strange and completely useless, obviously. The expected result is {{Negative|7}}.

This bug is fixed with the new preprocessor.

This is bug 5453.
