example for line breaking in @unpack docstring

[tpapp]

For structs with many fields, the fields should have a linebreak when the coding style precludes long lines. A possible syntax is

@unpack (a, b,
         c, d) = container

I am wondering whether the docstring of @unpack could benefit from an example like this. It is obviously not specific to this macro, but at the same time not trivial to figure out if one does not know the AST details.

Asking your opinion, would be happy to make a PR.

Does it not work without brackets? I'm not too fussed about this. But if you feel like it would improve the docs, then go for it.
