I am already making longlines.el use post-command-hook to process text
yanked *into* the longlines buffer.  But I need a separate mechanism to
process text yanked *out of* the buffer, and neither post-command-hook nor
after-change-functions are suitable for this.  By the time the hook is
called, the text has already been put into the kill ring and clipboard.

In that case, I don't think our ideas are so different.  I'll alter my
patch to implement the `kill-filters' variable, and make the appropriate
functions use it before calling buffer-substring.  So far, these functions
are `kill-region', `copy-region-as-kill', and `copy-to-register'; are
there others?
