Why adding obscure options for special cases, when the same results
can be achieved by a simple awk script like:

addr2line -Cfse executable addr1 addr2 addr3 ... | \
    awk '{ if (a++ % 2) print b " " $0; else b = $0 }'

In my opinion, a format option, if added, should be more generic, like
the '+' option for the date command.
