Change readelf's display of symbol names (when not in --wide mode) so that if they are going to be truncated then "[...]" is displayed at the end. Add a comment line option to disable this enhancement and restore the old behaviour.

+Normally when readelf is displaying a symbol name, and it has to
+truncate the name to fit into an 80 column display, it will add a
+suffix of @code{[...]} to the name.  This command line option
+disables this behaviour, allowing 5 more characters of the name to be
+displayed and restoring the old behaviour of readelf (prior to release
+2.35).
