Commit 9f9b17a4's strtosz() defaults a missing suffix to 'M', except it rejects fractions then (switch case 0). When commit d8427002 introduced strtosz_suffix(), that changed: fractions are no longer rejected, because we go to switch case 'M' on missing suffix now. Not mentioned in commit message, probably unintentional. Not worth changing back now. Because case 0 is still around, you can get the old behavior by passing a zero default_suffix to strtosz_suffix() or strtosz_suffix_unit(). Undocumented and not used. Drop. Commit d8427002 also neglected to update the function comment. Fix it up.
