Include location of sources in final output

[pooh22]

When debugging problems, I spend a lot of time figuring out where the template or source is located.
Some template files may be overridden by a copy under /layouts/
Some pages are generated from several partial templates.

It would help a lot if the output (perhaps as a debugging option) contains where the template xxx.html starts.

I was going to say I didn't think this was possible, but we could modify the templates before they are parsed and add this information. Maybe we could add this whenever we run in watch mode?

I still think this would be useful to have for debugging. As explained in the documentation, there are several possible locations for sources, like _default, or layouts in the hugo tree, or layouts in the theme tree. The order is well known, but when you're looking at a generated html output file, it helps if you know immediately where to look for the problem instead of going down the list of possibilities.

I agree. Not the simplest to solve, but we should try.
