But one could consider an empty argument as completely converted?
No, because POSIX says the argument must be a C integer constant, and
empty strings are not C integer constants. Similar reasoning applies for
floating point specs like %g, where POSIX says the argument is converted
as if by strtod, and for an empty string POSIX says no conversion is
performed by strtod.
For example scripts with `printf '%d\n' "$int"` will start erroring if int is
not defined
It shouldn't be that big a deal, as the change doesn't affect stdout.
The only issues are stderr and exit status, and that sort of script
typically ignores both.
OK assuming all the above, the NEWS change looks good.
thanks!
