This is nuts.  `finder-commentary' is file-specific.  Anyone
who uses it (and admittedly it is underused - most users know
nothing about its existence) uses it on multiple files.

You might have noticed recently a bunch of mails about having
multiple grep buffers etc.  Well this is even more important
than that - and simpler, as this is just file-specific.  Each
file should get its own finder-commentary buffer, named after it.
