Robert Watson 7d7d429762 If stat() on the terminal specified in utmp fails due to ENOENT, don't
print a warning, and set the idletime variable for the entry to -1;
then pick up the -1 later in sprint() and lprint() and ignore those
idle times by printing just whitespace.  When third party applications,
such as kdm, insert utmp entries, they sometimes use strings like ":0",
which can't be stat()'d and currently result in warnings that are
not helpful to the user.
