Creating automatic filename stamps

[Alan E. Davis]

Some years ago---in the early 90s---I was working on a project with a
number of files, moving files around and renaming.  I was able to cobble
together an elisp function to duplicate and extend the time-stamp
functionality, to good effect, to help me keep track of the sources of
changes.

   - Time-stamp the flle
   - Duplicate the previous time-stamp on the next line, (possibly in a
list)
   - "File-stamp": record the current file name
   -  Add the previous filename on the previous line, possibly as the head
of a list of all previous names for this file.

I need this functionality all the time, but I have lost the old
implementation.  It must have been simple, because I knew almost no elisp
at all.  But I believe I stole the "Time-stamp:" code, and modified it.

For years I have tried to locate another implementation.  It seems so
pivotal, to me, that I imagine others have implemented it, probably better
than I had.

I have given it a try, but have not even gotten close.  I would be grateful
for any suggestions how to go about implementing this functionality.

The use of corrupt manipulations and blatant rhetorical ploys ...---
outright lying, flagwaving, personal attacks, setting up phony
alternatives, misdirection, jargon-mongering, evading key issues, feigning
disinterested objectivity, willful misunderstanding of other points of
view---suggests that ... lacks both credibility and evidence.
