rpassword affected by partial password reveal when input is interrupted

rpassword maintainers were made aware of a possible issue with a partial password reveal when input is interrupted.

To quote @squell:

@conradkleinespel I've confirmed this problem with SequoiaPGP, which I think uses rpassword, e.g.:

Suppose we use pkill -9 sq in a different terminal right after the password has been typed in:

$ sq key generate --userid "barf" --with-password Enter password to protect the key: Killed $ hello^C

Where the password I typed in is "hello".

This has been fixed in version v7.5.0 and above.
