" Using the following VIM variables: {{{1
" g:is_bash if none of the previous three variables are
" defined, then if g:is_bash is set enhance with
" bash syntax highlighting
" g:is_kornshell if neither b:is_kornshell or b:is_bash is
" defined, then if g:is_kornshell is set
" enhance with kornshell/POSIX syntax highlighting
" g:is_posix this variable is the same as g:is_kornshell
" g:sh_fold_enabled if non-zero, syntax folding is enabled
" g:sh_minlines sets up syn sync minlines (dflt: 200)
" g:sh_maxlines sets up syn sync maxlines (dflt: 2x sh_minlines)
