   I may soon find a few hours to check on it in more detail, what I   
   saw so far is that you convert the 2:1 in place now.   
      
   But I played around with several TEXT2BIN variants and found the   
   5:4 encoding as the best compromise:   
      
   Base64 is restricted and may be just good for Big Endian machines.   
   [4:3] ratio=1.33   
      
   Herberts 4:3 is much better than Base64 but still got a ratio of [1.33]   
      
   Terjes 13:8 may be good for very large sources, but isn't easy to   
   make it an SMC variant, so the decoder needs to use a 2:1 before   
   [16:13] ratio=1.230769   
      
   My latest solution (best compromise for me yet) is [5:4] ratio 1.25   
   because it's easy to SMC it and it's much shorter than the [13:8].   
      
   So finally I'd recommend to use the 5:4 encoding.   
   it needs (the 5th root of 2^32 = 84.4485) ~85=0x55 characters.   
   It may use char0x22 " as start and end indicator and use 0x23..0x78   
   for en-/de-coding.   
   It's easy to make that an SMC-variant, and when once everyone got such   
   a tiny tool we could share binaries of any size either RM or PM or LM.
