WAD Copy/append adds a character

[samintz]

I was trying to use COPY to append data to a file.

copy foo.txt + foo1.txt foo.txt

C:\Program Files\LunaSA\foo\foo1.txt =>>! C:\Program Files\LunaSA\foo\foo.txt
     1 file copied

The foo.txt was a 0 byte file and foo1.txt contained 63 bytes. After the copy, foo.txt contained 64 bytes. There was a 0x1A byte appended at the end of the file.

If I use this code to append, it works correctly:

type foo1.txt >> foo.txt

WAD. COPY appends default to ASCII copies, which append a ^Z to the end. If you don't want that, use /B.

(This goes way, way back to early COMMAND.COM days.)
