I should have been clearer:

echo "\\"; // shows one backslash
echo '\\'; // shows one backslash

the backslash is a metachar in both single and double quoted
strings so regardless of the quotes used in order to write a
literal backslash in a string you must 'backslash' it.

you still not with me?:

echo '\'; // does this parse?

so the output of metaquote() is correct.
