tar on AIX with remote tape

[Joerg Lemke]

Hello,

I tried to use tar-1.13 on AIX 4.3 using a remote tape
on another machine. It did not work, so I had to fix
it in the source code as described below.

On AIX the RSH-program accepts argv[0] as "/usr/bin/rsh",
"/usr/bin/remsh", "rsh" or "remsh" for standard syntax.
Otherwise it assumes that argv[0] is a hostname and the
command takes the short form: "hostname command"

Due to the source code near:

#rtapelib.c, line 415
   ...
    remote_shell_basename = base_name (remote_shell);
    if (remote_shell_basename)
      remote_shell_basename++;
    else
      remote_shell_basename = remote_shell;
   ...

remote_shell_basename is set to "emsh" and then passed to
remsh as argv[0]. Hence the error message "host emsh not found"

I just removed the whole if-else for an interim solution, because
I cannot see the meaning of the ++.

Thanks for this otherwise very useful piece of software !
