[PATCH v6 0/3] MR8920: cmd: Fix some TYPE command behavior (one more try).
Giving this one final shot. If this is not deemed acceptable, I will abandon the effort and just move on to other things, no hard feelings. This is IMO a cleaner, more conservative/less invasive change. What is fixed: - Bug #56381, "TYPE c:\windows\winhelp.exe >foo", i.e. binary mode operation. I would probably consider this the main reason for this change. I'm trying to get the compiler mentioned in the bug report working. - Ctrl-Z termination of TYPE output to the console. - "TYPE con >foo", with Ctrl-Z handling, functionally equivalent to "COPY con foo". Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=56381 -- v6: cmd: Fix TYPE behavior (now uses WCMD_copy_loop). cmd: Refactor WCMD_copy_loop out of WCMD_ManualCopy, and stop copy loop at EOF for /a mode. cmd/tests: Add test to check for TYPE truncation in binary mode. https://gitlab.winehq.org/wine/wine/-/merge_requests/8920

I'm not sure it's worth it trying all possible input character as: - ASCII characters (20-7F) bring nothing - it could have some unwanted side effects depending on input locale for upper half of the values - tests should be tests, not tools to list all possible values (it also consumes test time) so I'd suggest that the second test duplicates the first one, but replacing ctrl-z by EOF=0 (so that we test unitary the behavior of the control characters that should end a file in text mode) and the third commit shall remove to todo_wine that are now passing Done.
