"python -c" returns 1 in case of an error. Use a return code of 2 if
the Neovim module is not found to distinguish these cases.
Verify the interpreter version before checking for an installed Neovim
module. Show a new error message if the Python interpreter version
is below the minimum required version.
Always use "pkgutil" to determine if the Neovim module is installed.
In contrast to "importlib", which was used for Python 3,
"pkgutil.find_loader" is available for all Python versions [1,2].
"pkgutil.find_loader" internally uses "importlib" for Python >= 3.3 [2].
Also, the previously used "importlib.find_loader" is only available
since Python 3.3 (so checking the major Python version was not enough)
and deprecated since Python 3.4 [3].
Finally, conditioning on the major version in Vimscript was incorrect,
as checking the Neovim module for a certain Python major version does
not mean that the tested interpreters are actually of that version.
For example, we test the "python" executable, which is Python 2 on
Ubuntu and Python 3 on Arch Linux.

According to the vim helpfile:
> fnamemodify({fname}, {mods})
> ...
> Note: Environment variables don't work in {fname}, use
> expand() first then.
So this causes issues if your $MYVIMRC contains environment variables
(e.g. $XDG_CONFIG_HOME)
Before, running Nvim in a directory containing a Python module `neovim`,
or one that is imported by it or a plugin, will load that module and not
the system one. So Nvim might be tricked into running arbitrary scripts
from the current working directory.
Fixes#1665Fixes#2530
I see that problem fixed by #2801 was resurrected by making help tags file
generated in a more direct way. This fixes the hang without using the empty
file.
vim-tutor-mode provides a mechanism to write and read interactive
tutorials in vim. It's aim is to replace the venerable vimtutor with a
more modern system.
The plugin's development is maintained at https://github.com/fmoralesc
/vim-tutor-mode
Closes#2351.
Also move introduction to Nvim and topic overview to nvim.txt.

There's no way this isn't some long-running joke:
"Just as ':print'. Was apparently added to Vi for
people that keep the shift key pressed too long..."
Note: A user command can overrule this command.
Regarding ':X': the command has been removed for a while, but the
documentation must have been missed, so remove it here.

- CPO_ALL and CPO_VI are identical, so merge them
- No longer check for the environment variable 'VIM_POSIX'
- In vim_diff.txt, mention the removal of 'cpoptions' flags
