A recent bug entitled
bug#51841: 27.2; erc-insert-marker has no value
(opened by Libera user Bost) was in part brought about by confusion over
whether ERC already offered this feature and perhaps applied it during
major-mode setup. While I don't think erc-stamp and erc-fill currently
provide sufficient support to rig up automated refilling in a reliable
way (on window configuration change, for example), I agree that some
means of doing so manually might occasionally come in handy.
A related issue concerns the purpose and treatment of the option
`erc-fill-prefix'. This one's a mystery to me and seems to have little
meaningful bearing on anything. It does make an appearance in
erc-button.el, but to what end I'm not entirely certain. Like a few
other puzzlers, it was present in much the same form back when ERC was
first ported to ye old CVS some twenty years ago (almost to the day)
[1]. Anyway, I will continue to investigate this. Thanks.

Subject: [PATCH 1/1] Add command to refill ERC buffers
* lisp/erc/erc-fill.el (erc-fill-buffer, erc-fill--refill,
erc-fill--refill-thread, erc-fill--remove-stamp-{left,right},
erc-fill--hack-csf): Add new command and helpers to refill ERC
buffers.
* lisp/erc/erc-fill-tests.el: Add new file containing tests for
`erc-fill-buffer'. Add some support files to test against in
lisp/erc/erc-fill-resources.
