REPL input broken

Question

REPL doesn't handle backspace character correctly, even backing up over the "user=>" prompt, yet apparently not being captured at all during evaluation. Also, this is what happens when I type "clojure " <----space, instead of "clojure-" <----dash, while trying to evaluate "clojure-version":

$ mono Clojure.Main.exe
Clojure 1.5.0
user=> clojure CompilerException System.InvalidOperationException: Unable to resolve symbol: clojure in this context
at clojure.lang.Compiler.ResolveIn (clojure.lang.Namespace n, clojure.lang.Symbol symbol, Boolean allowPrivate) (link: 0x00000) in :0
at clojure.lang.Compiler.Resolve (clojure.lang.Symbol symbol) (link: 0x00000) in :0
at clojure.lang.Compiler.AnalyzeSymbol (clojure.lang.Symbol symbol) (link: 0x00000) in :0

...and further input is ignored, requiring ^C to exit.

Markup mangled my bug report obviously, whoops. I meant that I hit space after asterisk clojure instead of a dash.

This has been a problem on Mono from the beginning.
I've asked several people about it, but I don't have a solution.
I'll put a query up on the mailing list and see if anyone has a suggestion.

For what it's worth, a C1. REPL comes bundled with Mono which works well. The REPL code is a 900-line program which uses a 1000-line getline library. The latter has no dependencies outside of the System namespace, which is good, but I have no clue as to how it'd work with MS .NET. Anyway, I've attached it for your consideration (path in Ubuntu "mono" package source is mcs/tools/csharp/getline.cs).
