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

Steps to reproduce:
0) acquire the 'test_before.sh' attatchment
1) C-x C-f test_before.sh
2) C-x C-p and M-C-\

The resulting script I get is 'test_after.sh':
- Only the 1st case is auto-indented correctly.
- Cases #2 and #3 are 'semi-indented'.
- Cases #4 and #5 are not indented at all.
- Case #6 is semi-indented.

Comments:
tested on emacs:
21.1.1
21.2.3
21.2.93

Please check the code I just checked in.
It fixes your testcase for me.  Tell me if you bump into other
such problems for different patterns,
