The ^C's have to be real cntrl-C characters,
a line with no text was not showing in output, so it is virtually empty, and
the big substitute says pick up:
- starting at the beginning of the line ^
- string1 \( +> \1
- and string 2 \( +> \2
- string 2 runs from beginning of line to first | (not | = [^|], any number = *, then |)
- string 1 is longer, runs to but not including first cntrl-C (not ^C, any number)
- the first ^C
but lay back down in their place:
- string 1 \1
- a line feed \linefeed
- string 2 \2
If that is possible, then a line with N texts is now a line of 1 text followed by a line of N-1 texts.
