Optionally set the textarea colours via $GNOME_SSH_ASKPASS_FG_COLOR and
$GNOME_SSH_ASKPASS_BG_COLOR. These accept the usual three or six digit
hex colours.
When serving a SSH_ASKPASS_PROMPT=none information dialog, ensure
then <enter> doesn't immediately close the dialog. Instead, require an
explicit <tab> to reach the close button, or <esc>.
ssh/ssh-agent now sets a hint environment variable $SSH_ASKPASS_PROMPT
when running the askpass program. This is intended to allow the
askpass to vary its UI across the three cases it supports: asking for
a passphrase, confirming the use of a key and (recently) reminding
a user to touch their security key.
This adapts the gnome-ssh-askpass[23] to use these hints. Specifically,
for SSH_ASKPASS_PROMPT=confirm it will skip the text input box and show
only "yes"/"no" buttons. For SSH_ASKPASS_PROMPT=none (used to remind
users to tap their security key), it shows only a "close" button.
Help wanted: adapt the other askpass programs in active use, including
x11-ssh-askpass, lxqt-openssh-askpass, etc.
- Retry kb and mouse grab a couple of times, so passphrase dialog doesn't
immediately fail if you are doing something else when it appears (e.g.
dragging a window)
- Perform server grab after we have the keyboard and/or pointer to avoid
races.
