Re: [Nmh-workers] Loop support in mh-format?

I think the %[...%] is by “JLR”?  do_loop() sets up an FT_DONE that's 1
rather than the normal 0 and then the end of fmt_scan() at finished:
checks if it's true and if so returns the next format instead of NULL,
but only #ifdef JLR.  Without that defined it appears to be ignored so
formatting stops at the first %].  Just from reading, not running, so
could be wrong.  Didn't spot a caller that bothered to check the return
for non-NULL and call again...

Cheers, Ralph.
