REPL syntax errors not cleaned up - double errors.

[GoogleCodeExporter]

The chained parser is not flushing input so if the indented parser finds an 
error you get two error messages. Just annoying, not fatal.

What steps will reproduce the problem?

1. Make a syntax error on the command-line

What do you see?

A second syntax error: 'unexpected right paren'

> !2
*** Error - 'unexpected !'
~ '<LazyProcedure: cond>'
~ '<LazyProcedure: <define>>'
~ '<LazyProcedure: catch>'
~ '<LazyProcedure: while>'
~ '<EagerProc: <|http://www.genyris.org/lang/system#read-eval-print-loop|>>'
: 
2 # Bignum 
*** Error - 'unexpected right paren'
~ '<LazyProcedure: cond>'
~ '<LazyProcedure: <define>>'
~ '<LazyProcedure: catch>'

What is the expected output?

Just one error message would be better.
