That is not very complicated except that...

... how is the “current rule in rc file” identified as an old code
line to be commented? Here I’ll assume it is the last but one line,
following your example, but I suppose it’s quite unlikely that it will
always be so. The “:MarkChange” command should be called while the
region to be processed is selected; it could be modified so it is
called on the old code (to be commented) and then find the limits of
the entire region by itself (e.g. with blank lines).
Also, the command can take an optional argument, the “keywords” line
to be inserted; if not given, the function will prompt for it.
" Put this in your .vimrc file.
function! s:markchange (kw) range
" Retrieve the one-line comment string, hoping it exists (could be
" defined otherwise, too).
let comment = matchstr(&comments, '[[:alnum:]]\@<!:\zs[^,]*\ze')
" Ask for keywords if not given when calling MarkChange.
if a:kw !~ '\S'
let keywords = input("Keywords, please?\n")
else
let keywords = a:kw
endif
let keywords = comment . "Keywords: " . keywords
" Comment the last-but-one line.
call setline(a:lastline-1, comment . getline(a:lastline-1))
" Append the end symbol; use :undojoin so ``u'' will undo
" the entire operation.
undojoin
call append(a:lastline, comment . "&&")
" Append the keywords and date lines.
undojoin
call append(a:firstline-1, [keywords, comment . "[Keydate:" .
strftime("%c")])
endfunction
com! -range -nargs=* MarkChange <line1>,<line2>call s:markchange(<q-args>)
" End of code.
I hope it helps.
Best,
Paul
