Google has a exciting surprise for users of its word processing product, Docs: Soon, it will be able to fix grammatically awful clauses like that.

The company is launching a new "grammar suggestions" feature in Docs that will catch and suggest corrections for all sorts of language slip-ups, including article errors ("a" versus "an") and more complicated concepts, like dangling subordinate clauses (for example, "After she drank her coffee" cannot stand alone as a sentence).
