POSIX[1] states that those commands must be written unconditionally: "If any 
replacements of '%' or '!' are performed, the modified line shall be written 
to the standard output before command is executed".

"Cannot open input file" belongs in the category of 'help messages', and is 
printed because your script has a 'H' command. The rest is the intended 
output, except "Newline appended", which will be fixed in the next release 
of ed in a few days.


Best regards,
Antonio.
