I am currently cleaning up a patch that implements LFUN_VC_RENAME and LFUN_VC_COPY for submission. I implemented it originally for my wife in 1.6, and do not want to port it on each upgrade;-) During the cleanup I stumbled over the file_ member of the CVS and SVN classes. RCS does not have it, and in CVS and SVN it is only sometimes used. As I understand it, it always points to the buffer file. I do not really understand why it exists at all. The history does not tell much, since it is there from the very beginning of the CVS class.
I'd like to unify the file name handling for all backends. In principle, file_ could be removed completely, or it could be moved to the base class and used exclusively (instead of owner_->absFileName() etc). Removing it is more safe (less changes, no internal file name refresh issues). Using it exclusively would pave the way towards using version control also for all kinds of included files, e.g. images, because the implicit coupling to the buffer file name would be gone. What do you prefer? Georg
