Format specifiers in SUDO_PROMPT are not expanded

[Pu-Anlai]

Hellohello! While format specifiers set through the -p argument are expanded, for SUDO_PROMPT they are printed literally.

$> sudo-rs -p "password for %p" -s
[sudo: password for user] Password: ^C

$> SUDO_PROMPT="password for %p" sudo-rs -s
[sudo: password for %p] Password: ^C

Expected behavior
-p and SUDO_PROMPT behave in the same way.

On a related note: It would be great if the passprompt sudoers setting could be implemented as well.

And finally: Thank you so much for sudo-rs!

Thanks for reporting this! We may consider splitting the feature request and bug report in one, but adding passprompt seems like it is easily done.
