Ah, this is clearer.  

Notice that regexp don't 'show' anything, they 'match' input.  It's
the program that use the regexp that may decide to show or hide lines
depending on whether a regexp match them.

Here is such a regexp matching any line but those containing "--":
  
           ^\([^-]\|-[^-]\)*\(\|-\)$
