Provides mappings to automatically close environments in TeX/LaTeX.
Pressing \c in normal mode (or <C-\>c in insert mode) will cause the last open environment to be closed.
(If a fold is started on the \begin{env} line, then it will be automatically
closed on the \end{env} line.)
Also pressing <C-\>} in insert mode when the cursor is at the end of a \begin{environment} will automatically generate a \end{environment}.
It will leave the cursor at the end of the \begin{environment} (in insert mode), so that the user can enter arguments [if any].
Small and functional. Suggestions welcome.
Drop the script into your $VIMRUNTIME/ftplugin directory for global instalation.
Put it in ~/.vim/ftplugin for local installation.
