tclx8.4 works fine with Tcl 8.5 and 8.6. It's just version, appended to the
package name. There were tclx8.3 and tclx8.4 in the Debian archive at
some point. So, that's not a problem to use tcl 8.6 and tclx8.4.

There could be, however some backwardly incompatible changes in
libtcl between 8.4, 8.5 and 8.6, so some testing is very desirable to check
if it's okay to migrate to the newer Tcl.

But anyway, Tcl 8.4 reached its end of life, so we have to do something.

Cheers!
