" b:is_kornshell               if defined, enhance with kornshell syntax
" b:is_bash                    if defined, enhance with bash syntax

"                                 b:is_kornshell is default
"   is_bash                    if none of the previous three variables are

" b:is_sh is set when "#! /bin/sh" is found;
" However, it often is just a masquerade by bash or kornshell.
" So, when the user to set "is_bash" or "is_kornshell",
" a b:is_sh is converted into b:is_bash/b:is_kornshell,
" respectively.
