Browse Source 
This adds expire and unlink fields to the PublicLink interface.

This fixes up the affected backends and removes unlink parameters
where they are present.

If successful, the last line of the output will contain the link. Exact
capabilities depend on the remote, but the link will always be created with
the least constraints – e.g. no expiry, no password protection, accessible
without account.
If you supply the --expire flag, it will set the expiration time
otherwise it will use the default (100 years). **Note** not all
backends support the --expire flag - if the backend doesn't support it
then the link returned won't expire.
Use the --unlink flag to remove existing public links to the file or
folder. **Note** not all backends support "--unlink" flag - those that
don't will just ignore it.
If successful, the last line of the output will contain the
link. Exact capabilities depend on the remote, but the link will
always by default be created with the least constraints – e.g. no
expiry, no password protection, accessible without account.
