" Variables {{{1

" Note: we create this variable in every script that accesses it.  Normally, I
" would put this in plugin/editorconfig.mnv.  However, in some of my tests,
" the command-line testing environment did not load plugin/* in the normal
" way.  Therefore, I do the check everywhere so I don't have to special-case
" the command line.
