to clarify: my intention was to have a backup to which I can revert if
necessary (and I don't have to go back to an original file which could be
hard to find)

I see 2 main scenarios:

a) convert-ly a single file - in my system I press ctrl+F11 (or the
corresponding pop-up item) and it's done. if for any reason I forget I've
already done this and I press this combination a second time my original is
gone.

b) convert-ly a full folder (eg. a piece with lots of files or the whole
LSR) - here I would copy the whole folder to a new one (mentioning the
version) and convert the original. if something goes wrong I still have the
original. for this I don't need a backup from LilyPond.

the choice of the backup's name is secondary - I'm happy with any of the
proposed versions (1 or 2 tildes).

now to the sophisticated mechanisms: if there is a (recognized) backup in
one or the other form in the *whole* folder, convert-ly should prompt for a
decision - numbered or not!? this is most likely beyond your (or my)
intention.

should we specify more clearly the risks of and how to handle convert-ly?
