I just had a situation where I needed to add several dozen strongarm variables (all pathauto) to a feature. It'd be very useful to be able to do something like this:

drush fa feature_name variable:pathauto*

I tried running the above without the asterisk which prompted me to show a list of all matches. That got me 191 results. I tried entering 1-191, but that just hung (I left it for a good twenty minutes and it never did anything). In the end I was force to manually click 191 checkboxes on the recreate feature admin screen. :-(

Also, it would seem there's no drush integration component available in the issue component list.
