Maybe call_editor() instead of edit_buffer()? Since we technically read
the file specified by "path" into the buffer "buffer", after having called
the editor.
Calling $EDITOR to edit the buffer is an implementation detail
of letting the user edit the buffer. I think the function name
should express what it does more than how it does it.
My suggested name does not convey the "letting the user" part,
though.
