updates block_example_block_info

I'm all in favor *if* and *when* #1045606: hook_block_info doc should use visibility constants goes in. I've subscribed. @droplet if you can provide a patch when that one gets committed it would be great.

I do hate that this would result in a fatal with any earlier version of D7 after we commit it.

I didn't realize these were already defined, so I'm fine with this. Patch awaited.

Thanks for the patch. You have to make the patch relative to root of the project directory (in the examples directory). That's why it failed to apply.

Fixed. Commit 556a3d06ac14c15bf31b5dac3399ec859de99c60

Technically, using BLOCK_VISIBILITY_LISTED adds a dependency to the Block module. Which is needed anyway if we're going to do anything with blocks, so I also added that to the dependencies in the block_example.info file.

This needs to go into 8.x too, doesn't it?

If you're not already using git cherry-pick, you'll probably want to.

Thanks for the awesome work on these.

I actually did cherry pick the commit and fixed this in 8.x-1.x, I just forgot to post the D8 commit number here. (Posting commit # is a new procedure for me, I'm going to forget once in a while.)

8.x-1.x commit 17880d5a3053d81c469ca25c1a3a1fc5d8c1e000
