[FIX] use version-client.texi for cvsclient.texi

[Alexey Mahotkin]

To get rid of Automake warning (and make the two documents use
appropriate last-modified date) please change

@include{version.texi}

to 

@include{version-client.texi}

or some other name matching "vers*.texi", as per Automake manual.
Then re-run Automake.  Here is ChangeLog entry:

2001-08-29  Alexey Mahotkin  <alexm@hsys.msk.ru>

        * cvsclient.texi: Use version-client.texi instead of
        version.texi.
