[Tagging] Follow-up on Time Domains

[Brad Neuhauser]

I don't think three letters is quite as universal as you think.  It's also
really common in English to use M,T,W,T,F,S,S (in context) or
M,Tu,W,Th,F,Sa,Su or variations.  Since we have a defacto OSM standard with
two letters (the opening_hours key has over 100K uses), and it's
unambiguous, this seems like a case of "if it ain't broke, don't fix it"
