This command toggles the member buffer between short and long display form. The short display form displays member names, only:
| isEmpty contains hasMember create | storeSize hash isEqual restoreGuts | saveGuts
The long display shows one member per line with member name and regular expressions matching the member (if known):
| isEmpty Bool isEmpty () const... | hash unsigned hash () const... | isEqual int isEqual (...
Regular expressions will only be displayed when the Lisp database has
not been produced with the ebrowse option ‘--no-regexps’.
