installed.

Always set VIMEDITOR_SVRNM environment variable.
Identify Neovim in VIMEDITOR_SVRNM.
Update knitr options.
More specific message when v:servername undefined.
Set value of VIMEDITOR_SVRNM inside StartR().
Update.
Use "Neovim" instead of "NeoVim".
Enable messages from Neovim to vimcom.plus.
The Vim-R-plugin now can send messages to R if running in Neovim.
Current known bugs affecting Neovim:
  - Omnicompletion and completion of function arguments don't display
    the pop up menu with the list of completions.
  - Multiline messages don't display completely. Only the last line is
    shown.
The vimcom.plus package still cannot send messages to Neovim. It can
only reply to messages received from Neovim.
Update.
On Windows, only load vimcom.plus if TMPDIR is set.
New file: nvimcom.py (Neovim messages to R).
