editors/nvi2: Update to 26-Apr-2024 (52c07e8)

 - In ruler show the current line number as a percentage of the
   total lines

 - Link macro for hyperlink

 - Add showfilename set option

 - Fix undefined string comparison

 - Replace Clang-only __builtin_is_aligned with C code

 - Use memmove to realign buffers

editors/nvi2: Explicitly use db18

The default (db5) has been deprecated for some time.

MAN?PREFIX: eleminate its usage  and move man to share/man

editors/nvi2: Update to V2.2.1

    https://github.com/lichray/nvi2/releases/tag/v2.2.1

Changes since V2.2.0:

 - Display control chars in altnotation.

 - Intuitively jump between troff paragraphs.

 - Keep correct count for unprintable character sequences in
   opts_print().

 - Do a full reformat when ^L/^R redrawing.

editors/nvi2: Fix "move forward paragraphs" (}) with numeric prefix

Two github issues identified the same problem:

    https://github.com/lichray/nvi2/issues/118
    https://github.com/lichray/nvi2/pull/119

For example typing "}" three times on this sample text:

.PP
1
.PP
2
.PP
3

editors/nvi2: Fix core dump when tags file pattern has a trailing '\'

If you create a tags file of a macro that ends with a '\' and tag
for it, vi dumps core. For example:

    zinc 76 % cat test.h
    #define LATIN2PLAIN(ch) (((u_char)ch) >= 0x80 ? \
       pgm_read_byte_far(pgm_get_far_address(latin2plain) + \
       (((u_char)ch) - 0x80)) : (isprint(ch) ? (ch) : '_'))
    zinc 77 % ctags test.h
    zinc 78 % vi -t LATIN2PLAIN
    Segmentation fault

The problem is that the loop variable is unsigned (size_t) and it
gets decremented twice: 1 -> 0 -> 4294967295

Apply the upstream patch to solve this:

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

editors: remove 'Created by' lines

  *  Chris D. Faulhaber <jedgar@fxp.org>

*/*: Remove redundant '-[0-9]*' from CONFLICTS_INSTALL

The conflict checks compare the patterns first against the package
names without version (as reported by "pkg query "%n"), then - if
there was no match - agsinst the full package names including the
version (as reported by "pkg query "%n-%v").

Approved by: portmgr (blanket)

Remove # $FreeBSD$ from Makefiles.

Regular USE_GITHUB cleanup.

editors/nvi2: fix build on GCC architectures

Use newer GCC:
cc1: error: unrecognized command line option "-Wno-dangling-else"
cc1: error: unrecognized command line option "-fcolor-diagnostics"

-fcolor-diagnostics is incompatible with GCC, compilation works fine with Clang
also without it.
