Hello Charles.

The problem is not win32console by itself, but IRB:

irb -f --noreadline

Disabling readline functionality solves the problem, but affects 
autocompletion one, which is a bummer

Until someone can came up with a pure-ruby readline library that replace 
the buggy C one, I think there is no easy solution.

Sorry for not being more helpful.
