Bash Version: 2.05
Patch Level: 0
Release Status: release

Description:
Using "case ... esac" inside a $( ... ) collect does not work
because bash-2.05 interprets the ')' of the first 'case' pattern
as the closing parenthesis of the $( ... ) collect.
The shell's parsing is incorrect.

Repeat-By:
----- input to bash-2.05
foo=$(
  case $bar in
  */*) echo 1 ;;
  *)   echo 2 ;;
  esac
)
----- bash-2.05 complaint
syntax error near unexpected token `;'
line 3: `  */*) echo 1 ;;'
-----
