I don't think so, because it bombs if given a non-numeric value.

    $ [ "Y" -ne "0" ]
    -bash: [: Y: integer expression expected

This would break anyone who is currently passing an arbitrary non-blank
string as the ppphint argument.

Of course, the documentation should probably be made consistent:

  .IP ppphint
  If you put an integer > 0 here, radtest (or actually radclient) will
  add the attribute \fIFramed-Protocol = PPP\fP to the request packet.

  If you put a value other than empty string or "0" here ...
