Bug#234107: Status of @ sign in Morse code

[Ben Harris]

It looks like ITU-R has taken over International Morse Code and it's now 
specified in ITU-R Recommmendation M.1677-1 (10/2009):

http://www.itu.int/rec/R-REC-M.1677-1-200910-I/en

The footnote on page 1 claims that the definition of morse code in ITU-T 
Recommendation F.1 has been withdrawn, which would leave M.1677-1 as the 
best official definition of International Morse Code.

M.1677-1 includes a code for '@', which I hope is definitive enough for 
the maintainer to add it to morse(6).  Of course the manual page will need 
to be updated to refer to the new standard.
