[EM] the subject line prefix

[Rob Lanphier]

Well, for some reason, around this time last year, as many of you surely 
noticed long before I did, the subject line prefix got changed to 
[Election-methods] instead of [EM].  This was not intentional.  I 
suspect what happened was something got reset in a software upgrade or 
other lower-level configuration, and I didn't notice it because I 
haven't had time to read the list in quite a while.

So, it should be back to [EM].  Sorry for the inconvenience, and feel 
free to complain if something like this changes without notice from me 
again.
