OK. (but only *if* the patch should  be accepted ...)

Because that requires the command definition to be done locally or in a 
library.
The point of the patch is not to make original breaks *possible* but to make
them *available*.

Yes, but not as a "command line option" but using the -e option defining 
the configuration variable

IMO these are different things.
The detailed aspects of an original edition are a matter of a style 
sheet - if you want to mimick them.
What I am talking about is a tool to improve the user experience for 
music entry or proof-reading. It is extremely practical to have 
identical breaks when you have to match the original manuscript and the 
compiled LilyPond output in a score of 100+ pages. But of course you 
don't want to hardcode these breaks and prevent LilyPond from doing its 
own breaking.
So what I want is a way to be able to enter the original manuscript's 
breaks in the input file and switch them on and off.

And I would really love to see that being part of LilyPond itself and 
not only possible to implement in a library.
Firstly because I would like *all* LilyPond users to have that available 
and secondly because I would like to add this as a Layout Control Option 
to Frescobaldi.
