Thank you very much for the clean-up of the import_stata module. The
changes are all improvements.
The canonical Stata test dataset is
http://www.stata-press.com/data/r9/auto.dta which is an 5KB dataset on
automobile models. It features both variable labels for all variables
and value labels for the one factor variable (The variable "foreign"
can take on the values "Foreign" and "Domestic"). rkward successfully
imports auto.dta (from the internet as well as from a local copy).

I agree. The only reason I could see is for completeness. It's an
option in the underlying R function read.dta(). We could add a snarky
remark to the dialogue box.

Thanks, and it's helpful for me so see the rewrite that concatenates $options

Nice. Thanks, and it's good for me to learn this.
