The 'a', 'i' and 'c' commands take a literal text to be added followed by backslash, but then in the source we cannot indent the literal text which makes it ugly. We need to also remember to double the backslash inside double quotes. Avoid these issues altogether by having an extra line in a template file and generate test vectors by deleting the line or replacing the line and not using the 'a' command.
