bug#48193: Youngsters in charge of emacs vs. basic Bourne shell "for" statement

[積丹尼 Dan Jacobson]

for i do
    true
done
    : This line and the whole rest of the program misindented because emacs 
shallow knowlege of shell grammar.
    : Test with TAB. Emacs only knows about:
    for i
    do
        true
    done
    : If this was python, well, you would have to have the language change to 
accomidate emacs.
    : Also if we are colaborating on a big project we cannot just rip up line 
of other peoples code so
    : they are not misindeted for only us.
    : Yes, some emacs programmers do not know shell grammar and just assume... 
indeed the word "do" on the
    : first line is not even in a different color. But the word in right here 
in this line is! Three times!
    : Hmmm, [including this part of] the sh language is, maybe 50 years
    : old. Not something checkbashisms --extra --force --posix has an issue 
with. It is part
    : of sh, bash, dash, ksh, ...
    : I.e., not something invented before emacs...
    : What could be even older? Well, sh must have been written in C...
    : Yes, I reported this before. But it was closed by programmers who
    : do not know basic Bourne shell "for" statement grammar.
    : emacs-version "27.1"

Indeed, I was just reading in RISKS Digest,
