This patch fixes an issue whereby a newline character appearing within a hidden input field is incorrectly reinterpreted as a space character. The patch handles almost all cases, and includes a test case. 15/18 tests pass, but the remainder currently fail due to the fact that ELinks does not currently support textarea scripting.
