This patch add '-p' argument with the arch prefix, in order to call
target-specific readelf for bloat-o-meter report. It is useful when cross
compiling busybox with specific toolchain, in case host's native readelf
does not work. '-p' help msg is leveraging linux kernel's bloat-o-meter.
For
This patch switches arguments parsing to argparse module, which makes it
easy to extend further arguments into this script. Note that one thing is
changed: how additional parameters is pass-through to readelf, now it needs
an assignment char '=' followed by a pair of single/double quotes to wrap
is missing in our variant is support for -p "ARCH-PREFIX-" for
> readelf. Should probably switch to argparse too.
argparse and prefix sounds cool! Thanks Bernhard, i will add this to my
todo list.

Change the outout of bloat-o-meter, line wrapped at maximum 75 columns;
including 'function/old/new/delta' title and numbers, seperation line with
'-', and the last line 'Total'. Also put 'Total' numbers to the last column
in order to keep it aligned with previous 'delta' numbers.
Consider this

way, loop is not required in my previous length counting script :)
simply pipe to awk is fine:

This patch replaces the 78 "-" prints with 75 "-". And replace the 80
columns summary line with 77 columns. ("%s" is considered as two chars
and should be filled with whitespace " ", so 77 = 75 + 2)
Consider this scenario: a patch contains the output of "bloat-o-meter" to
clarify about the size

Found previous patch accidentally adds 'x' permission to file 'crond.c',
attached v2 patch would not change permissions of file 'crond.c',
