    Hi, Erik.

    my_getpw(uid/gid) and applets used it have problem:
    if username for uid not found, applets can`t detect it
    (but code pessent). Also "%8ld " format is bad:
    spaces not required (applets have self format
    or spec format (tar applet) and overflow for "id" applet...)
    This problem also pressent in stable version.
    Patch for unstable in attach.
