doc: typos

[akim demaille <akim@…>]

This page:

http://www.boost.org/doc/libs/1_56_0/doc/html/BOOST_VARAINT_MAX_MULTIVIZITOR_PARAMS.html

is really fishy. Really, "VARAINT", not "VARIANT"? "VIZITOR", not "VISITOR"??? "BOOST", not "BOOOOST"?

That's indeed what the code reads:

#ifndef BOOST_VARAINT_MAX_MULTIVIZITOR_PARAMS
#   define BOOST_VARAINT_MAX_MULTIVIZITOR_PARAMS 4
#endif

but what's the point?

Also, the end of http://www.boost.org/doc/libs/1_56_0/doc/html/variant/tutorial.html#variant.tutorial.recursive about multi visitation is not clear to me. Typically, it seems that bool_like_t what meant to be used, but is not.

Unfortunately BOOST_VARAINT_MAX_MULTIVIZITOR_PARAMS can not be changed, because such change will break user's code.

Multi visitation section in Tutorial was right, but I've simplified it a little bit ​in develop branch.

Hi.

Still, it should fairly easy to do something like this:

#ifndef BOOST_VARIANT_MAX_MULTIVISITOR_PARAMS
  // Bugward compatibility.
# ifndef BOOST_VARAINT_MAX_MULTIVIZITOR_PARAMS
#  define BOOST_VARIANT_MAX_MULTIVISITOR_PARAMS BOOST_VARAINT_MAX_MULTIVIZITOR_PARAMS
# else
#  define BOOST_VARIANT_MAX_MULTIVISITOR_PARAMS 4
# endif
#endif

// Bugward compatibility.
#undef  BOOST_VARAINT_MAX_MULTIVIZITOR_PARAMS
#define BOOST_VARAINT_MAX_MULTIVIZITOR_PARAMS BOOST_VARIANT_MAX_MULTIVISITOR_PARAMS

and drop dead typos.
