sh-script ksh option skeleton bug + a few suggestions

[Klaus Zeitler]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

1. start emacs -q --no-site-file
2. C-x C-f x.ksh
3. Insert "Options Loop", i.e. C-c C-o 

the code inserted from skeleton looks like:

while getopts :ab OPT; do
    case $OPT in
        a|+a)
        
        ;;b|+b)
        
        ;;*)
        print "usage: ${0##*/} [+-ab} [--] ARGS..."
        exit 2
    esac
done
OPTIND-1$(( OPTIND - 1 ))


I've attached a patch to fix this.

This patch also contains the following improvements:

1. add "select" to bash sh-other-keywords

2. correct ";;<label>" in skeletons for "Options Loop" and "Case Statement"
   to ";;\n<label>, i.e. change the skeleton "Case Statement" from e.g.

case $b in
    x1)
    
    ;;
    x2)
    
    ;;*)
esac

to

case $b in
    x1)
    
    ;;
    x2)
    
    ;;
    *)
esac

and similar for "Options-Loop" skeleton

3. add an empty line after "elif" lines in skeleton "If Statements"


Furthermore I'd suggest to set sh-heredoc-face to font-lock-doc-face.
Also I wonder why skeleton-end-hook is modified. I can't see any advantage.
Normally I can decide via skeleton-end-newline if a final new-line should
be appended or not, but sh-script-mode doesn't allow that.


And one OT question: My last followups to gnu.emacs.bug didn't show up.
Is it not possible anymore to post directly to gnu.emacs.bug and do I
have to send followups to bug-gnu-emacs@gnu.org instead?

And here's the patch:
