> ~/.authinfo.gpg exists, and corresponding keys exist with gnupg to

> start emacs with 'emacs -Q', execute:
> ```
> (set 'epg-pinentry-mode 'loopback)
> (icomplete-mode 1)
> ```
> Type 'C-x C-f /ssh:'.
> In the minibuffer appears the prompt 'Password for [GPG KEY]: '.
> 
> At this point the expected behaviour is for this epg prompt to accept
> the user's password input, decrypt the authinfo file and carry on with
> the TRAMP path entry.
> 
> Attempting to input the password results in:
> - Each character entered switches the minibuffer between displaying the
>   epg prompt and displaying the 'find-file' prompt.
> - Each character entered when the 'find-file' prompt is visible is added
>   to that prompt's input.
> - No characters appear to be added to the epg prompt - no '*'s appear
>   before the cursor.
> For example, if the user types '1234567890abcdefg' then the 'find-file'
> prompt will be displayed, with the text '~//ssh:24680bdf'
> entered. That's every other character of a password in plain text on the
> screen and nothing useful going on. 
> 
> I have found a work-around for this issue:
> Type any character into the epg prompt when it appears (this character
> will neither end up in the epg prompt nor the 'find-file' prompt), then TAB when
> the 'find-file' prompt returns. The epg prompt reappears and the
> password can be typed as normal from this point. 

João, any comments or suggestions?
