eps backend in latest master

[Kevin Barry]

Hi all,

I used to have a style file for creating musical examples (typically, for
printed books and the like) that handily produced cropped images by setting
the backend to eps (and removing margins and headers and footers). I
noticed that this has stopped working in latest master and I am unable to
exactly replicate the behaviour. The crop option does not preserve the
space between systems so it's no good. Is there another way to get the old
behaviour?
