Broken revert for newstyle (grouped) standalones

[Laetitia Gangloff (Acsone)]

Hello,

with the last version of the recipe I am not able to load standalone addons in a specific target.

If I defined a directory path like this:
[addons_additional_path]
recipe = z3c.recipe.mkdir
paths = ${buildout:directory}/addons-additional

and I try to get my addons like this:

git https://github.com/acsone/stock_scanner.git ${addons_additional_path:paths}/stock_scanner 7.0

where stock_scanner is a standalone addon.

I get the following error:

"Standalone addons such as stock_scanner are now supported by means of the explicit 'group' option. Please update your buildout configuration. "

Hmm, ok, I go to read the doc and adapt my code to get only this line :
git https://github.com/acsone/stock_scanner.git stock_scanner 7.0 group=addons-additional

And now, it is an exception that appears :(

Hi, and welcome !
At first I feared that I had forgotten to push the new doc, but apparently not.
I'll take a look at your branch in an hour max.

The doc is a little bit complex for me, but it is here, and I finally get something that works.

Sorry, if it was not clear.

Thanks for the contribution. Just merged your fix.
I'm changing the title for emphasis on revert, because that was the issue, finally
