RenameDialog: Show if files are identical
Compute and compare three hashes in the files : - beginning of the files - middle of the files - end of the file
I hope this is sufficient for close to perfect results. I am hesitant to add more intermediate hash, like compute an hash each QB or at chunks each 10% of the file size.
BUG: 412662 FIXED-IN: 5.73
After
Identical files:
Files that have differences:
Could be a base to add a form of "skip identical files" or "Overwrite non-identical files" when doing a batch copy.
