I just quickly made this simple terminal application i call 1Space.gambas
it converts text to only have one space between words.
' Gambas module file

Private bReading As Boolean

Public Sub Application_Read()

  Dim sTxt As String
  bReading = True

  While Lof(Last)
    sTxt = Last.ReadLine()
    Print Split(sTxt, " ", Null, True).Join(" ")

  bReading = False


Public Sub Main()

  If Args.Max Then
     For c As Integer = 1 To Args.Max
       Print Split(Args[c], " ", Null, True).Join(" ")
    Wait 0.1 ' give the pipe a chance to set bReading if there is a pipe.
    While bReading
      Wait 0.1



I can use...

1Space.gambas "Test   tooo    many     spaces"

and also

echo "Test   tooo    many     spaces" | 1Space.gambas

Cool , I did not know how to do that till i read this thread :)
