It's not just that particular use case that I have in mind.  As I wrote 
earlier, the feature I have in mind should not be an additional (minor or 
major) mode, but a core feature, adding the possibility for Emacs users to 
open multiple files in a single buffer, in a way that would be as 
transparent as possible to everything else.  Or, in other words, to work 
on a list of buffers as if it were a single buffer.  Otherwise it would 
indeed be necessary to reimplement many (possibly all) commands, and other 
problem would have to be resolved, with a result that would likely be too 
inefficient.

My question was: Is this feasible, or is the one-to-one correspondence 
between buffers and files too deeply rooted in Emacs' codebase that it is 
not feasible?  If it is feasible, could this feature be considered for 
implementation in a future Emacs version?
