The reason for these being nested is so that we can embed the entire examples/templates directory, including subdirectories (see #1669), without also including the source code of the examples Go package itself. As far as I can see, the embed package doesn't provide a way to recursively embed a directory while also excluding a configurable subset of files.

I figured the inelegance of an extra level in the directory hierarchy was better than the inelegance of bundling files that never get used, but YMMV.

Removing this nesting would require filtering out non-directories in examples.List instead, and also reverting the documentation changes that were made in #1715.

@dwahler would embed ./*/* include the source code itself?

The user experience is a bit odd with the nesting because it appears that examples is just a package. Having these at an upper-level fixes it I think.
