Here is a patch which (hopefully) adds a new file, providing the drush command for reverting views.
It works like this:
[prompts the user with a list of overridden views to choose from, or to revert all]
drush views-revert archive myview2
[reverts the two specified views]
I've tested it quite a bit, but further testing couldn't hurt. It has checks for making sure the view is in overridden, and stuff like that. A code review could not hurt either.
Note: I've created the patch using the instructions from the Git instructions tab, hopefully it will work!
