patch 7.4.2164

Problem:    It is not possible to use plugins in an "after" directory to tune
            the behavior of a package.
Solution:   First load plugins from non-after directories, then packages and
            finally plugins in after directories.
            Reset 'loadplugins' before executing --cmd arguments.

searched for the "plugin" sub-directory and all files ending in ".vim"
will be sourced (in alphabetical order per directory), also in
subdirectories.
+ However, directories in 'runtimepath' ending in "after" are skipped
+ here and only loaded after packages, see below.
Loading plugins won't be done when:
- The 'loadplugins' option was reset in a vimrc file.
- The |--noplugin| command line argument is used.
- The "-u NONE" command line argument is used |-u|.
- When Vim was compiled without the |+eval| feature.
Note that using "-c 'set noloadplugins'" doesn't work, because the
commands from the command line have not been executed yet. You can
- use "--cmd 'set noloadplugins'" |--cmd|.
+ use "--cmd 'set noloadplugins'" or "--cmd 'set loadplugins'" |--cmd|.
Packages are loaded. These are plugins, as above, but found in the
"start" directory of each entry in 'packpath'. Every plugin directory
found is added in 'runtimepath' and then the plugins are sourced. See
|packages|.
+ The plugins scripts are loaded, as above, but now only the directories
+ ending in "after" are used. Note that 'runtimepath' will have changed
+ if packages have been found, but that should not add a directory
+ ending in "after".
+
5. Set 'shellpipe' and 'shellredir'
The 'shellpipe' and 'shellredir' options are set according to the
value of the 'shell' option, unless they have been set before.
