May be you misunderstand the use of * here, that do not have the same
meaning that in shell like *.el.(globbing).

| `*'

|      to match the preceding regular expression repetitively as many
|      times as possible.  Thus, `o*' matches any number of `o's
|      (including no `o's).
| 
|      `*' always applies to the _smallest_ possible preceding
|      expression.  Thus, `fo*' has a repeating `o', not a repeating
|      `fo'.  It matches `f', `fo', `foo', and so on.

Have a look at the elisp manual about regexps.
