Hi Patrick,

Are you sure you've diagnosed the issue correctly? From what I can see
the name of the environment variable is always TWITTER_PAT, at least
in the current rtweet release (0.7.0). get_tokens calls twitter_pat
(https://github.com/ropensci/rtweet/blob/v0.7.0/R/tokens.R#L120) and
twitter_pat hard-codes TWITTER_PAT
(https://github.com/ropensci/rtweet/blob/v0.7.0/R/tokens.R#L371). In
short I don't see anything suggesting that the name of the environment
variable includes a user name at all.
