bug#11582: 23.4; sh indentation wrong for main() function

[twb@cyber.com.au (Trent W. Buck)]

To reproduce:

  1. run "emacs -Q tmp.sh"
  2. enter the following text

       foo () {
           foo
       }

       main () {
           foo
       }

  3. use C-x h C-M-\ to reindent everything.

  4. observe that sh-mode indents incorrectly:

       foo () {
           foo
       }

       main () {
               foo
           }

16:59 <forcer> twb: For some reason, after main () {,
(sh-get-indent-info) returns two function indentations.

In addition to version the below, this issue does not appear in GNU
Emacs 23.3.1 (arm-unknown-linux-gnueabi) of 2011-08-15 on cushaw,
modified by Debian.

A bash script with a main() function has commits from me ca. Dec 2009 to
Mar 2010, and they are indented correctly (four space), which indicates
that whatever Emacs I was using at the time was not affected.
