theoretically the prompt could be "password for <user>" or
"<user>@<domain>'s password:" or whatever ... pam leaves everything
open. whether something is even a _password_ prompt at all can be only
determined by checking whether the pty has echo on or not (not that it
is likely that su would ask anything else).

therefore the _real_ solution would be reimplementing kdesu using the
model i recently used for kdesktop_lock (and kdm). that's quite a bit of
work, though.

for now, i think matching "password.*: *$" case-insensitively is ok.
note that the matched buffer should contain the newline, if one was
read (so it does not match the prompt regex).
