* Read a line from s_in, starting at index *pcount in buf. Start by
* printing prompt on s_out. If the string is longer than size - 1 (we need
* 1 extra byte at the end for a null or an EOL), use bufmem to reallocate
* buf; if bufmem is NULL, just return 1. In any case, store in *pcount the
* first unused index in buf. *pin_eol is normally false; it should be set
* to true (and true should be recognized) to indicate that the last
* character read was a ^M, which should cause a following ^J to be
* discarded. is_stdin(s) returns true iff s is stdin: this is needed for
* an obscure condition in the default implementation.
