I would like to request that this question be reopened: Compare two files and append the differences at the end
Justification
As originally asked, the question was vague and unclear, linking to large external data files and requiring a fair amount of analysis to understand the point of the question. As edited, it now asks a clear and precise question, with a simple example and and a complete description of the expected output.
What I did so far
I have followed the steps listed at How do you reopen a closed question:
I edited the question so that it is much clearer and no longer too broad, in my opinion.
My mistake: I first did minor edits but only got to a good quality question after several edits, so the reopen reviewers probably didn't see it in its current state.
I would like to flag the users who cast close votes to ask them for either an explanation or reconsideration, but none of them commented on the question so I cannot actually flag them.
This meta question is my last resort: ask for reopen here via the "support" tag. In meta.SE, it seems to say use the "reopen-request" tag, but I didn't find one, so I'm hoping putting it in the subject line will do.
