Bash Version: 4.2
Patch Level: 46
Release Status: release

 Section of 'case' in bash's man page says:

 case word in [ [(] pattern [ | pattern ] ... ) list ;; ] ... esac
              A  case  command  first expands word, and tries to match it 
against each pattern in turn, using the same matching
              rules as for pathname expansion (see Pathname Expansion below).

but that is not correct, the matching here does NOT follow pathname expansion, 
the treatment of "/" is not the same.
Man page should explain that '/' is treated specially in pathname expansion but 
not in case pattern
matching.  For example '/test/*' will match even '/test/one/two/three' in case 
matching, but NOT in path name matching
where "/" is a "separator" and stops matching.

  case matching on '/test/*' also matches '/test/one/two/three', if it was true 
pathname matching, it should not match, only /test/
*/*/* would match in that case.

        either change case to do pathname matching, like doc says, but that 
would probably break many existing scripts. OR, correct
 the docs and explain that pathname matching is not possible in bash, i.e. 
there is no 'fnmatch' builtin to bash.
