config overrides new section with a __DELETED__ value is added verbatim

[pellcorp]

So this is unlikely to happen in real life but I have reproduced it.

So if a overrides / patches file has a section with a deleted value (__DELETED__), but the section does not exist at all in the target
file, the section including the key with the DELETED will be added verbatim, this should be fixed even if its unlikely to happen in the wild.

Below is a really simple example.

A printer.cfg:

[section]
key: value

A overrides.cfg:

[section2]
key: __DELETED__

Will result in a printer.cfg with:

[section]
key: value

[section2]
key: __DELETED__

What really should probably happen is if there are any keys in the overrides file where the value is __DELETED__, completely ignore that section.

Also this happens if you have a section: DELETED for a file that does not allow section deletes, in that case should ignore the override rather than verbatim apply it.
