if errorlevel is a >= comparison; if errorlevel 0 always succeeds and is meaningless.
Also fix the find command; the copy tests were actually failing, but failures were masked by the errorlevel thing. This commit is the same as in !8588, it's needed by both.

Without that, find ignores all arguments, and instantly returns errorlevel 1 and no output.
Other builtins and programs may also react to invalid stdin; I didn't investigate it. --- programs/cmd/tests/batch.c | 10 +++++++++- programs/cmd/tests/test_builtins.bat.exp | 16 ++++++++-------- programs/cmd/tests/test_builtins.cmd.exp | 16 ++++++++-------- 3 files changed, 25 insertions(+), 17 deletions(-)

the fixes for DEL are ok (still need to decide upon overlap and comments from MR8588) (side note: internally `errorlevel` is a signed integer, and can be set to a negative value. so, generally speaking, `if errorlevel 0` is still a valid and meaningful statement and is not always true; AFAICT DEL's doesn't set errorlevel to a negative value)

Technically true, but accepting both zero and (some) nonzero errorlevels is quite implausible. If such behavior is desired, it should be rewritten to if %errorlevel% geq 0, or prominently commented.
In this case, they're clearly intended to be equality comparisons.
