Enable copy/paste/creation of folders and files in admin://

When running nemo with elevated privileges using admin:// the creation of files or folders is not allowed.

We can see this was changed in this commit: https://github.com/linuxmint/nemo/commit/161c54fbe54deb0609ea38b227ddaec84e137937:

nemo-view.c: Disallow creation of folders or files in admin:// -
it does not properly set file permissions (the same reason copy/paste
is not allowed either.)

I am not sure whether this is a feature request or a bug but the current behavior when browsing with elevated privileges is inconsistent and confusing. Files/folders can be deleted but not created.

I am not sure the exact semantics of the file permission issue, but if an admin user can accomplish the same thing in a terminal, shouldn't he be able to do it in nemo? Otherwise one could argue that admin:// access should be removed period. That would be consistent.

Thoughts? comments?

Start with nemo-view.c and the referenced commit 161c54fbe54deb0609ea38b227ddaec84e137937 to understand why creation and copy/paste were disabled for admin://. Trace the existing delete path and permission handling, then establish whether safe consistent file operations can be supported; done means the behavior is consistent without incorrect permissions.
