It would be nice if tclsh had a built-in cross-platform readline type

You could try using 'rlwrap'.
I start my tclsh as

%rlwrap tclsh

and then all the arrow keys CTRL +A etc seem to do the right thing.

Have a look at http://wiki.tcl.tk/16139.

If you have X or other windowing
system available, I recommend
tkcon. Lots of convenience features.
