[ESS] TWITTER API environment variables

[Patrick Connolly]

G'day Ista,

Thanks for setting me straight on that.  I was misled by the fact that
my username on this machine is pat.  Something led me to believe that
the twitter environment would be TWITTER_WORK but I don't have remote
access to check (and be disabused of that notion).

In any case, the problem seems to have vanished.  I'm a bit
uncomfortable not understanding why the problem arose and disappeared
with no error message.  I've wasted hours on this issue.

Best

Patrick
