than what?  What alternatives have you considered?  How is the buffer-save
triggered (is it triggered by a timer, by the user selecting the buffer and
hitting C-x C-s, by some other command in the main ERC buffer, indirectly by
save-some-buffers, ...)?

How about choosing the file name based on the date the buffer is created?

How about using "foo/bar-latest at first and switching to "foo/bar-<date>"
in before-save-hook?

How about always using "foo/bar-latest" as buffer-file-name and
link/copy/move the file to "foo/bar-<date>" in after-save-hook?

How about using "foo/bar-<date>" at buffer creation and in before-save-hook
update the "<date>" part if necessary (if the date only includes the month,
it's unlikely to change, and if the user restarts Emacs every day, the same
will hold even if the date includes the day)?

Hmmm.... doing it in a timer?  That sounds like trouble,
