Splice script 

If there is a "history merge" script that can take parameters, I'd like to modify  so that all you have to do is click on a link to activate the script.  The link would be pre-populated by the editor who placed the histmerge request with things like
 Merge-to page
 Merge-from page
 Starting edit of merge-from page to be merged in (default: oldest edit)
 Ending edit of the merge-from page to be merged in (default: newest edit)
 Any other parameters that are needed for the script.
If I can figure out how to do it, the updated histmerge template would show an alert if there were overlapping edits and/or edits that, by virtue of edits not included in the starting-to-ending range, edits which the requester indicates should be discarded.  As I don't have admin access, It would be helpful to have a copy this script to study it and someone willing to beta-test it when it was ready for testing. /(talk)/(contribs)
