A curious one is nvi, which uses the Berkeley DB RECNO

access a text file as an array of lines (RECNO = record number).
On FreeBSD as least, "nvi" is used instead of "vi" (and is linked).
And oddly enough, BDB is exactly how I would have implemented it... The
basic datum is a line after all (I have no idea about EMACS, and don't
want to know) so it makes sense to use a structure that can rapidly access
arbitrary line numbers.
