Also:
- Insert some missing words;
- Strive for consistency with capitalisation of words;
- Improve shell alias examples.
The gvim words were left alone for now, but they deserve to
be treated like proper names, GVim or GUI Vim, unless these
refer to executable filenames (on *nix systems).

Problem: [security] disallow setting env in restricted mode
Solution: Setting environment variables in restricted mode could
potentially be used to execute shell commands. Disallow this.
restricted mode: disable allow setting of environment variables
Setting environment variables in restricted mode, may have some unwanted
consequences. So, for example by setting $GCONV_PATH in restricted mode
and then calling the iconv() function, one may be able to execute some
unwanted payload, because the `iconv_open()` function internally uses
the `$GCONV_PATH` variable to find its conversion data.
So let's disable setting environment variables, even so this is no
complete protection, since we are not clearing the existing environment.
I tried a few ways but wasn't successful :(
One could also argue to disable the iconv() function completely in
restricted mode, but who knows what other API functions can be
influenced by setting some other unrelated environment variables.
So let's leave it as it is currently.

Problem: inconsistent feature description
Solution: delete old mentioned feature sets small and big
The may however still be mentioned for historical reasons. e.g. The
last Amiga built version is for Vim6.2 and is still a big version.

Problem: It is not easy to see what client-server commands are doing.
Solution: Add channel log messages if ch_log() is available. Move the
channel logging and make it available with the +eval feature.
Problem: There is no way to start logging very early in startup.
Solution: Add the --log argument. Include the date in the start message in
the log file. Avoid a duplicate message when forking. Log an
executed shell command.
Problem: OS/2 and MS-DOS are still mentioned, even though support was
removed long ago.
Solution: Update documentation. (Yegappan Lakshmanan, closes#5368)
Problem: Remarks about functionality not in Vi clutters the help.
Solution: Move all info about what is new in Vim or already existed in Vi to
vi_diff.txt. Remove {not in Vi} remarks. (closes#4268) Add
"noet" to the help files modeline. Also include many other help
file improvements.
Problem: Can execute shell commands in rvim through interfaces.
Solution: Disable using interfaces in restricted mode. Allow for writing
file with writefile(), histadd() and a few others.
