bug#61192: Emacs 28.1: Bash Shell Script Indenting does not recognize if, [....]; then

[Stephen Montsaroff]

Since upgrade to Emacs 28.1, I have noted an annoy change in
shell-script mode auto-formatting.

I would like to recover the old behavior

Before, if I entered

if [ "$x" = "" ];then
    export x=$y
fi

and then enter new line, the new line would align with the fi

if [ "$x" = "" ];then
    export x=$y
fi
cp fred ethel

Now it I do the same thing I get the new line indented

if [ "$x" = "" ];then
    export x=$y
fi
    cp fred ethel

The matching code also does not recognize that the
fi is connected to the then statement.

This is not the case if I break the if into two lines or add a leading
space to the ;

if [ "$x" = "" ]
then
    export x=$y
fi
cp fred ethel

if [ "$x" = "" ];then
    export x=$y
fi
cp fred ethel
