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.

man page, separated from the rest of the manpage by an empty comment,
like so;
.\" $Id$

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
