Instrument comint input fontification with this diff: diff --git a/lisp/comint.el b/lisp/comint.el index f47e6089f2..c83da95ad2 100644 --- a/lisp/comint.el +++ b/lisp/comint.el @@ -4083,7 +4083,10 @@ comint--fontify-input-fontify-region nil (lambda (beg end) (unless (get-text-property beg 'comint--fontify-input-inhibit-fontification) - (font-lock-fontify-region beg end verbose))) + (font-lock-fontify-region beg end verbose) + ;; Output contents of the visible portion of the + ;; buffer to *Messages*. + (message "%S" (buffer-substring-no-properties (point-min) (point-max))))) beg end))) (`((jit-lock-bounds ,beg1 . ,_) .

Press "C-p C-p C-e" to move point to "date" and change it into "datee". Open up *Messages* and find the following strings: "date" "date " "datee Sun Nov 27 01:05:27 PM CET 2022 ~$ " These strings represent the context in which shell fontification was performed on the input. The last one includes "Sun Nov 27 01:05:27 PM CET 2022\n~$ ", which is a mistake that this patch attempts to fix. However, in pretty much all cases, this didn't result in any user visible inaccuracies, since shell fontification of a command rarely depends on the contents of the lines that follow it. >> Not that my copyright paperwork renewal is currently in progress, but I >> hope that the number of lines in this patch fall below the threshold. > > Since when your previous assignment became outdated?
