bug#2837: 23.0.91; tramp: ssh passphrase vs. password

bug#2837: 23.0.91; tramp: ssh passphrase vs. password

[trentbuck]

Just now I tried to open /ssh:dhcp98:/ and it asked me for "dhcp98's
password".  It *should* have asked me for the passphrase for one of my
SSH keys (id_rsa).  This either means that the prompt is misleading
(i.e. it wants my passphrase) or worse, that it genuinely wants to use
password-based authentication (i.e. ignoring my key).

Hmm, now it prints:

    Passphrase for /ssh:dhcp98:

So I guess I just misread passphrase as password this morning...
FWIW, here are the details you requested.  Sorry to bother you!

tramp-version is a variable defined in `trampver.el'.
Its value is "2.1.15"

I'm using the version that shipped with my emacs-snapshot: GNU Emacs
23.0.91.1 (i486-pc-linux-gnu) of 2009-03-30 on elegiac, modified by
Debian.
