But one can simply open the file in Microsoft EDIT (the successor to
EDLIN) and then resave it, and it inherits CRLF properties.

Yep.

I have verified this many times, when I used to use ZTerm on a Mac
2SI.

I use a generic c program whenever I need to convert one character to
another... I just compile up whatever I need and throw it in
/usr/local/bin with a good name for next time! So far I have:

cr2lf
lf2cr
tab2cr
space2cr
space2underline
underline2space

#include <stdio.h>
#include <strings.h>
void main(void){
   char spud;
   while (spud!=EOF) {
      spud=getchar();
      if (spud==13) {
         spud=10;
      }
      putchar (spud);
   }
}

Other fun stuff:
ctrl2dot (replaces unprintables with dots)
Foldcase
FOLDCASE
foldcase (these three change words to all lower, all upper, or First
Letter After A Space Uppercased)
deSpace (strips spaces)
