So I've step into something which might be at least in part a feature,
but contains some elements which really aren't helpful.

The setup is this, a Makefile file containing

> DB += file.db

This directory also contains three files.

* file.substitutions
* file.template
* other.template

So two with the same basename.

> $ cat file.substitutions 
> file "file.template" {
> {X=1}
> }
> file "other.template" {
> {X=2}
> }
> $ cat file.template 
> # from file.template
> $ cat other.template 
> # from other.template
> $

What I expect to see is

> $ cat file.db
> # from file.template 1
> # from other.template 2

What I actually see is

> $ cat file.db
> # from file.template 1
> # from file.template 2

msi completes normally.  No warnings are printed.

The second filename 'other.template' is silently ignored!
In fact, I find that all the filenames in the .substitutions
file are ignored!  So 'file "invalid" {' produces the same
output, and emits no warnings.

However, 'filexxx "invalid" {' triggers a syntax error as it should.

I've reduced this to a difference in how msi is called.
The unexpected comes from:

> msi -I. -o file.db -Sfile.substitutions file.template

If I renamed 'file.template' to eg. 'filex.template' then
the invocation is:

> msi -I. -o file.db -Sfile.substitutions

which produces the expected results.

So the immediate solution is to rename the .template file.

I am curious though to find out how much of this is defined,
or at least expected behavior?
