minor typ-o in the manual

[Alex Sassmannshausen]

Hello,

I think I spotted a minor typ-o in the (texinfo) @settitle manual
section:
3.2.4 '@settitle': Set the Document Title

[…]
  When the title page is used in the output,[…]  Thus, the two do not
  need not match exactly. […]

The last quoted sentence should probably read either 
Thus, the two need not match exactly.
- or -
Thus, the two do not need to match exactly.

Hope this is helpful.

Best wishes,
