* enable you to separate a file-name into its component *
* strings (CBL_SPLIT_FILENAME), and to join strings *
* together to form a file-name (CBL_JOIN_FILENAME). *

* This sets up most of the parameters you need for a join
* The join below replaces the original extension in split-buffer
* with the extension in ext-buffer, and puts the result in
* join-buffer.
