bug#33336: 26; Document how to restore trashed files

[Drew Adams]

I tried to answer this question, knowing nothing about trashed files:
https://emacs.stackexchange.com/q/37492/105

I can understand that if files are trashed to the system recycle bin
then perhaps Emacs cannot help users much in telling them how to restore
trashed files (or can it?).

But if `trash-directory' is non-nil then can't (and shouldn't) Emacs
tell users how to restore files trashed there?  Is there an Emacs
operation that does this?  If not, can a user just move a file from that
directory to another (IOW, are trashed files normal files)?  And is
there some way for a user to know what the original location was for a
trashed file?

In sum, is there something that Emacs can offer users, in terms of
helping them restore trashed files?
