Of course it it's not feasible to embed a complete Bourne shell interpreter (or for that matter the interpreter of any language) in Emacs to cope with every possible exotic construct of that language. I note that for i do true done and for i; do true done are both indented as you expect. ^ permalink raw reply [flat|nested] 6+ messages in thread
