magic-string@0.16.0 or later versions breaks buble

[kzc]

buble works correctly with magic-string@0.15.2.

buble fails 41 tests with magic-string@0.16.0.

3f6dd4d is the commit that breaks buble.

@Rich-Harris I recommend to leave buble with the older version of magic-string for now until the entire PR backlog is merged into buble.

@kzc Agree. Apologies I haven't been very responsive on that project recently – would be very happy to give you the commit bit if you'd like, just let me know

@Rich-Harris Thanks, but I'm good as a drive-by patcher for now. I am only using buble as a faster babel 5 and it addresses the ES6 feature subset I need.

I think 3f6dd4d alters the magic-string move() behavior in some way. The destructuring transforms in particular use fairly complicated inserts, remove()s and moves()s and may rely on some unforeseen side effects of the previous implementation.

This can be closed now that you migrated bublé to magic-string@^0.22.4.
