When I'm reviewing suggested edits, I occasionally encounter suggestions for questions that are on hold. These suggestions tend to tidy the question up a bit, fixing a bit of grammar and formatting. I understand these editors are trying to help, but it seems like wasted effort when the author has not stepped in to fix the primary problem that led to the question being put on hold.
I've accepted many such edits on the principle that a) it's pretty harmless, b) it encourages helpful participation, and c) the author might come back and fix the main problem, making the edit helpful in the future. But on the other hand, this sort of edit may be too trivial to be worth encouraging. And the effort would be more helpful if it were directed towards tidying questions that are not being closed.
How do you handle these cases?
