Hi, some headers allow short form:

  From = f
  To = t
  Via = v
  ...

To detect those cases I match header names of one letter length, but will it 
be valid for the future?

I mean: is it possible that in the future it appears a header with a short 
form of 2 letters? like:

  New-Header-Name = nh

?


Thanks a lot.
