Hi.

I wasn't aware that use of indirect buffers is frowned-upon. Mostly
they've been working pretty well for me.

I usually use it to simultaneously look at different places in the same
file. Most of the time this is some long source code thing. It's nice to
have separate kill rings, mark rings, narrowing, etc.

The only issues I've encountered have to do with various functions not
recognizing that those buffers have a backing file. Those are
ff-find-other-file, vc-diff, etc. I suspect that making
(buffer-file-name) work for indirect buffers would resolve a lot of
these, but I don't know enough about the internals to propose that.
