    text-encoding: Clarify whitespace-stripped encoding
    
    The previous code was correct, because g_strstrip() modifies a string in
    place, but it looked wrong. Separate the call to g_strstrip() so that it
    doesn't look like we are comparing the unstripped string in the second
    call to strcmp().
