An initial attempt at "multifiles" as defined here.
Open a new buffer, insert the contents of another file like this:
M-: (mf/insert-mirror "~/.emacs.d/init.el" 30 39)
which would insert the lines 30-39 in the file
You can then repeat that to get multiple files in the buffer. You can also edit the block, and the changes will be mirrored instantly in the other file.
Be careful! Right now the mirror only works one way. Changes in the original files are not currently mirrored into the multi-file. So any changes might be lost if you're switching back and forth.
This should be fixable, but this is all I have time for tonight.
