Yay! Be liberal in what you accept!  (I've always been annoyed that '-m
1g' complains, forcing me to us '-m 1G').

Okay, we're at the end of the series, and I've pointed out other
possible improvements.  As mentioned elsewhere, it might be nice to add
a 25/24 to match coreutils, which allows 'm' and 'mib' to mean
1024*1024, vs. 'mb' to mean 1000*1000.  Right now, all clients of
qemu_strtosz() are stuck to one scale, vs. letting the user choose a
scale by their choice of suffix.  But it does not hold up this series if
you don't like the idea.
