However, for subprocesses used by > Lisp programs [...] Wouldn't this just reiterate what the text already says? [...] However, for subprocesses used by Lisp programs for internal purposes (i.e., with no user interaction), where significant amounts of data need to be exchanged between the subprocess and the Lisp program, it is often better to use a pipe, because pipes are more efficient, and because they are immune to stray character injections that ptys introduce for large (around 500 byte) messages. [...] This explicitly says that pipes are preferable when NO user interaction is done, especially when large amounts of data are to be exchanged with Emacs. I don't think that asking for a password is a special case in this context.
