manpages: consistent syntax
In the manpages, bold is used to denote characters the user has to enter verbatim, italic denotes placeholders and non-highlighted pieces are used as a structure: "[]" specifying an optional part, "{}" a mandatory part, with "|" used for alternations. The "!" for negation is better supported before the option than after it, too. The patch makes a few files consistent with this style already used in manpages.

This module matches IPv6 extension headers and/or upper layer header.
.TP

Matches the packet which EXACTLY includes all specified headers. The headers
encapsulated with ESP header are out of scope.
-.IR header
-can be
-.IR hop | hop-by-hop

-.IR route
-(Routing header),

-(Fragment header),
-.IR auth
-(Authentication header),
-.IR esp
-(Encapsulating Security Payload header),
-.IR none
-(No Next header) which matches 59 in the 'Next Header field' of IPv6 header or any IPv6 extension headers, or
