Wrong indentation of statements after certain case labels in sh-mode.

Wrong indentation of statements after certain case labels in sh-mode.

["Schöpflin, Markus"]

In GNU Emacs 21.2.1 (i586-suse-linux, X toolkit, Xaw3d scroll bars)
 of 2003-03-28 on Cameron
configured using `configure '--with-gcc' '--with-pop' '--with-system-malloc' '--prefix=/usr' '--infodir=/usr/share/info' '--mandir=/usr/share/man' '--sharedstatedir=/var/lib' '--libexecdir=/usr/lib' '--with-x' '--with-xpm' '--with-jpeg' '--with-tiff' '--with-gif' '--with-png' '--with-x-toolkit=lucid' '--x-includes=/usr/X11R6/include' '--x-libraries=/usr/X11R6/lib' 'i586-suse-linux' 'CC=gcc' 'CFLAGS=-O2 -march=i586 -mcpu=i686 -fmessage-length=0 -pipe 	 -DSYSTEM_PURESIZE_EXTRA=25000 	 -DSITELOAD_PURESIZE_EXTRA=10000 	 -D_GNU_SOURCE ' 'LDFLAGS=-s' 'build_alias=i586-suse-linux' 'host_alias=i586-suse-linux' 'target_alias=i586-suse-linux''

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

Shell script case labels containing [] are disturbing the indentation of
statements following the case label. If you take the following code snippet
and indent it in sh-mode, the second case label triggers the bug. The
indentation is ok for the rest of the case statement, though.

case xyz in
  
  foo)
    echo foo
    ;;
  
  [bar])
  echo bar
  ;;
  
  foobar)
    echo foobar
    ;;
  
  *)
    echo default
esac

I cannot reproduce it on the current Emacs.

Indentation does not work at all if I insert only this snippet. The
sh-mode is obviously failing to find a name of the shell.

If I add a "#!/bin/bash" in the first line, indentation works OK.
