Remove doc on removed feature

README.md

 
     Note that there is no risk damage to data integrity, it's
     just that the routine is unable to show you desired value.
-
-
- *  if `debug -v "x*:` is used, `x*` apparently tries to match
-    *filenames* first, and only if there is no match, it goes
-    on to match variable names.  This does not seem to affect
-    `@`, though.
-
-    Probably some eval pitfall.  For now I'll just remove `*`.
-    If somebody can fix it, we can re-add it.
-
-    On the other hand, I don't even understand how `*` should
-    exactly behave compared to `@`, so having it disabled does
-    not seem like such a loss.  And by the way, did you know
-    that the eval is evil?  So in the end, maybe we should not
-    have this feature in the first place... :)
