Please tell more about this "separator character": what should it be and how will it be displayed? And what is its purpose in the first place? I'd like to avoid adding a general format-style extension to the native line numbers, that's a kind of creeping featurism that will eventually slow down redisplay too much, something that the display-line-numbers implementation explicitly attempts to avoid. People who must have the full-fledged format capability could simply use linum-mode instead. > I would be happy to try to contribute code but I'm unsure of where > to start with such a task. The code is in xdisp.c, if that's what you meant to ask. Thanks.
