/*
* wr_fputs - like fputs(), but makes control characters visible and
* turns \n into \r\n.
*/
void
wr_fputs(char *s) {
char c;
#define PUTC(c) if (carefulputc(c,stdout) == EOF) goto err;
while(*s) {
c = *s++;
if (c == '\n')
PUTC('\r');
PUTC(c);
}
I will see about adding an option flag to disable the CR and write
check for the flag setting in the one or two places 'wr_fputs' is
invoked.
