Dear Emacs maintainers, I have been working on a major mode derived from comint-mode. The mode uses redirection to show documentation in a separate buffer. Sometimes, a prompt would appear in the output of the command producing the documentation and this would end the redirection prematurely. Searching among variables in comint-mode I found comint-redirect-finished-regexp and its docstring made me believe that I could set it to change the end of redirection. However setting it had a no effect and looking at the sources I found that this is because it is set by comint-redirect-setup and comint-redirect-send-command-to-process calls comint-redirect-setup so that it is always set to comint-prompt-regexp during redirection. This is confusing behavior because docstring of comint-redirect-finished-regexp gives no clue that setting it will have no effect. Similarly the docstring of comint-prompt-regexp states that its value is only used when comint-use-prompt-regexp is non-nil but that is not true for redirection. Overall I think it would be nice to have an optional argument to comint-redirect-send-command-to-process which allows a user to explicitly pass the regexp to use for ending redirection. Another issue I had was that I wanted to run some commands when redirection ended. There didn't seem to be any hooks that accomplished this but from source of comint-redirect-preoutput-filter I found that comint-redirect-hook is run when redirection finishes. However comint-redirect-hook is not defined as a variable and nothing seems to give any hint of its existence.
