It does so to evaluate a ~user in a path and I guess that's what other
apps do as well.  This is kind of weird since it would obviously not be
necessary to enumerate accounts for this functionality:

  if (~ in path)
    if (~ is solo)
      getpwuid(getuid ())
    else
      getpwname (username after the ~);
