Current code requires entering a newline character in order to continue past DIR /P prompts. This change allows any key to be pressed instead.
Code to handle this was similar to existing WCMD_pause() so we leveraged that code for this purpose as well. Key to the fix was the removal of ENABLE_LINE_INPUT from the console flags, and ENABLE_PROCESSED_INPUT was added in order to preserve the ability to abort the operation via Ctrl-C.
