It is a common convention to make the first argument the command
name without its path, and this change breaks that convention.
Does it matter, or would it break something? I recall that some
implementations of shell (e.g. "bash") change their behaviour
depending on how they are invoked (e.g. "ln -s bash /bin/sh" makes
it run in posix mode) but I do not know if they do so by paying
attention to their argv[0]. There might be other fallouts I do not
think of offhand here.
I do not have an objection to what these patches want to do, though.
Thanks.
