Hi Sébastien,

please test the attached patch against master.

It creates a new command `org-insert-last-stored-link'
bound to `C-c M-l'.

You can use `C-2 C-c M-l' to insert the last two links.

So the set of commands around inserting links would be:

  C-c l       => store link (the suggested user binding)
C-c C-l       => insert a link
C-c C-M-l     => insert all links as a list
C-u C-c C-M-l => insert all links as a list and keep them
C-1 C-c C-M-l => insert the last stored link
      C-c M-l => short for the previous keybinding

I also find myself in this workflow:

1. collect various links through a session
2. store the last one for a new task
3. dump all links into some "read later" heading

so I think this feature deserves to be in core.

What do you and others think?
