1.
Exactly what I did
I created an entry in an org file.
I added an attachment to that
entry.
I used refile (C-c C-w) to move the
entry to another org file.
I visited that file and attempted
to open the attachment (C-c C-a o).
2.
What I expected:
Because there was only one
attachment associated with the entry, I expected it to open.
3.
What happened instead:
I was prompted for an attachment
name. Hitting <tab> showed “no match” in the minibuffer.
