Subject: Shell-script mode doesn’t like redirection at
 beginning of command
Date: Wed, 23 Dec 2020 11:33:18 +0100

The “for” and “echo” in the following example are not font-locked in
shell-script mode, despite being syntactically valid.  (From my
experience, the “>&2 echo ...” idiom is quite common in practice, too.)

    >/dev/null for i in {1..5} ; do
        echo $i
    done
    >&2 echo 'Error!'

Additionally, the “for” and its “done” are not matched so the SMIE
grammar also needs fixing.

Best regards,
Dario

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I'm unable to reproduce most of this -- do/done seem to be matched, and
echo is font-locked.  (I tried this in Emacs 25.1 -> Emacs 29.)  The one
thing I can reproduce is the missing font-locking of the "for" keyword.
