- Small packaging simplifications
- Lets enable selinux

- Added patch to fix build on SLe_12_Sp3 and openSUSE_Leap_42.3
* joe-4.6-nonvoid-functions.patch

- Fixed broken build: Added patch which was forgotten to add to version control.

- Add Patch joe-4.6-desktop_files.patch: Desktop Category was wrong.
- Update to version 4.6
* Upgrade to Unicode 10.0.0. Add configure environment variable that allows
you select Unicode 8.0.0, 9.0.0 or 10.0.0.
* Install Gnome .desktop files for JOE. This allows you to use JOE in GUI
"Open With" mouse actions.
* Support strikeout and double-underline attributes for the few terminal
emulators that support them. Use "stricken" and "dunderline" in the syntax
files, or \s and \z in help screens and status line.
* Fix bug where JOE would sometimes crash when editing shell scripts. This
was due to an obscure bug in the syntax highlighter: 'reset' command (used
for default state) was incorrectly messing with stack.
* -highlighter_context was missing from many file types, which negated some
improvements from the previous version.
* Fixed signed char overflow with old style mouse events in large windows
* Fix bug where path restart (//) was being applied to block filter command
prompt. Strange things would happen if you had adjacent slashes in command
arguments.
* Allow ~ expansion but suppress path restart (//) in compiler error parsing.
Restore default handling of SIGPIPE and SIGINT for shell commands. This
fixes an issue where SIGPIPE doesn't terminate a process as expected, for
example by the head -n 10 in: ^K R !sh -c 'while :; do echo y; done' |
