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.

@item -T
@itemx --silent-truncation
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).
