Lispref version info.

[Aidan Kehoe]

lispref.texi has this; 

@titlepage
@title XEmacs Lisp Reference Manual
@c The edition number appears in several places in this file
@c and also in the file intro.texi.
@c This manual documents XEmacs 19.14 and 20.0 and was based on the
@c documentation for FSF Emacs 19.29 (v2.4).
@subtitle Version 3.3 (for XEmacs 21.0), April 1998

and several other references to the 1998 and XEmacs 21.0. I think this info
should probably be generated by the build process--perhaps inserting the
last modification date of any of the relevant source files in the title
page, to give people an idea of how old the data is.

when we say something in public? No-one!” -- Danny O’Brien
