This is an example which showing how this patch wrapped line to 75 columns,
use awk to count the line length and prepend it to each line's head[1].
Before applying this patch, the seperation line and summary line are 
wrapped to 78 columns:

72 crond_dummy_func                                       -     211    +211
72 .rodata                                            59300   59404    +104
72 crond_main                                           704     709      +5
72 static.crond_dummy_local_int                           -       4      +4
72 crond_dummy_global_int                                 -       4      +4
78 ------------------------------------------------------------------------------
78 (add/remove: 3/0 grow/shrink: 2/0 up/down: 328/0)             Total: 328 bytes

After applying this patch, the seperation line and summary line are 
wrapped to 75 columns:

72 crond_dummy_func                                       -     211    +211
72 .rodata                                            59300   59404    +104
72 crond_main                                           704     709      +5
72 static.crond_dummy_local_int                           -       4      +4
72 crond_dummy_global_int                                 -       4      +4
75 ---------------------------------------------------------------------------
75 (add/remove: 3/0 grow/shrink: 2/0 up/down: 328/0)          Total: 328 bytes

done < <(~/busybox/scripts/bloat-o-meter ~/busybox_unstripped_{orig,fix});
