shells/ksh: Update to 1.0.7

From the announcement email:

Full changelog at:
https://github.com/ksh93/ksh/compare/v1.0.6...v1.0.7

Main changes between 1.0.6 and 1.0.7:
- Fixed a hang in command substitutions (introduced in 93u+m/1.0.0)
   that was triggered when redirecting standard output within a
   command substitution, in combination with other factors. E.g.,
   the following no longer hangs:
         { v=$(redirect 2>&1 1>&9); } 9>&1
- Fixed a crash on trying to append an indexed array value to an
   unset name reference, e.g.: nameref unsetref; unsetref+=(foo
   bar). This now produces a "removing nameref attribute" warning
   before performing the assignment.
- Fixed: assignments like name=(...) to arrays did not preserve the
   array and variable types; similarly, assigning an empty set () to
   a compound indexed array caused the -C attribute to be lost.
- Fixed incorrect rejection of the tab key while reading input
   using the 'read' built-in command.
- Fixed a bug in printf %T: when using dates and times in the past,
   time zones for the present were incorrectly used, ignoring
   historical changes.

shells/ksh: Update to 1.0.6

From the announcement:

This is an urgent bugfix release that fixes a serious regression in
pathname expansion, see: https://github.com/ksh93/ksh/issues/660
The previous 1.0.5 release is withdrawn and should not be used.

Main changes between 1.0.5 and 1.0.6:

- Fixed a serious regression in pathname expansion where quoted wildcard
   characters were incorrectly expanded if a pattern contains both a brace
   expansion and a variable expansion.
- Fixed a bug where the command to launch a full-screen editor (^X^E in
   emacs and 'v' in vi) could cause the wrong command line to be edited

shells/ksh*: Fix ksh 1.0.5 Regression (issue #660) version 2

From the upstream patch description:

Patch version two. In mac_copy(), don't internally backslash-escape
a backslash in a glob pattern bracket expression. This also fixes
the #549 regression reintroduced by the previous patch, at least for
standard glob patterns. For this, we need to use the bracketexpr flag
(introduced as a copyto() local variable in 6c73c8c) in mac_copy(),
so we move it to the Mac_t struct, making it globally accessible.
Initialisation is automatic.

shells/ksh: Fix ksh 1.0.5 Regression (issue #660)

From issue #660:

Globs are not expanded with the following:

% echo "/"{bin,sbin}"/*"
/bin/* /sbin/*

% v=/; echo "$v"bin"/*"
/bin/*

But globbing is unexpectedly performed if both parameter substitution
and brace expansion are present:

	% v=/; echo "$v"{bin,sbin}"/*"
	[output omitted for the sake of brevity]

shells/ksh: Update 1.0.4 --> 1.0.5

The release email outlined the following changes:

This release has a large amount of bugfixes compared to 93u+m/1.0.4. In
summary:

- Fixed various bugs causing crashes.
- Fixed many bugs in the emacs and vi line editors, in command completion,
   and in file name completion.
- Fixed various bugs in the handling of quotes, backslash escapes and braces
   when processing shell glob patterns (e.g. in pathname expansion and
'case').
- ksh now throws a panic and exits if a read error (such as an I/O error)
   occurs while trying to read the next command(s) from a running script.

shells/ksh*: Remove BROKEN for missing sbrk()

As of Jan 26, 2021, ksh (ksh93/ksh) no longer needs sbrk(). Remove
BROKEN for architectures that don't have sbrk(2). See upstream issue
https://github.com/ksh93/ksh/issues/154.

shells/ksh*: Update descriptions

Update ksh ports descriptions to more accurately reflect what they are.

shells/ksh: Update 1.0.3 --> 1.0.4

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.

shells/ksh: Add missing option

Fixes:		6e9237ba47f0c0df54a58ca8a1bf79b44d580208

shells/ksh*: Allow the ksh ports to coexist

Add an option to allow the ksh ports to avoid conflicting with each
other and to coexist. This allows people who wish to punish themselves
by tracking developent to still be able to fall back should upstream
cause regressions.

This also allows legacy ksh93 to coexist with the recently added
ksh93/ksh, which is not entirely compatible with legacy ksh. Applications
which require a legacy ksh compatible package should use the ksh93 port
installed using one of its options. This allows new and old to exist on
the same system.

shells/ksh93: Introduce new ksh port

Now that ksh development has resumed under a new account on github,
this introduces the fourth stable release (1.0.3) of ksh93/ksh to ports
