VIS_HTTPSTYLE is a new encoding style for use in vis(), strvis() and
strvisx() that escapes characters according to RFC 1808 (URI encoding).
Since decoding of these require different detection of start-points of
escaped characters, VIS_HTTPSTYLE can be given as flag to unvis().
unvis() will then properly decode URIs.
A new function appeared, strunvisx(): strunvisx() behaves similar as
strunvis(), with one exception: It has an additional flag parameter,
which is passed to unvis() to archive the effect I described above.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Use the correct .Bx (BSD UNIX) or .At (AT&T UNIX) macros
instead of explicitly specifying the version in the text
in a bunch of man pages.
