Parse a single backslash (\) character and the character after.

If the character after the backslash is special, always ignore the backslash and return the escaped character.

Otherwise, if the backslash is not in quoted string, the backslash is ignored and the character after is returned. If the backslash is in a quoted string, the backslash and the character after are both returned.
