I agree with that sentiment. When I update patches, I rearrange the
results of "mkpatches", so that "cvs diff" only shows real changes
(and the revision history, after committing, makes sense).

If you do as I do, there's no harm in reviving a long-dead patch file
as a different patch.

Eh? If you put all patches in a single file, it'll be practically
impossible to get anything useful out of CVS. That's at odds with the
rest of your position.

How about if just we let "mkpatches" match up filenames and preserve
CVS tags?
