bug#2061: 23.0.60; Add preference to force load of Elisp files when they are newer than corresponding byte-compiled file

[Richard M Stallman]

    modified the .el file?

If you have written changes which are incomplete and not ready
to be executed.

This feature gives you control over when to start running your
changes: you control it by when you compile the files.  It is
important and it is easy to use.
