This way the regexp is beyond me, too. Fortunately, it is well
documented in the ange-ftp.el sources.

The problem is that the line you've digged does not contain a group
id. That's why, "kfs 0" is regarded as a date.

Same problem. "kfs 10" is regarded as a date.

"kfs 100" is not a date because "100" exceeds the range of days :-)

I've submitted a fix which should solve your problem. I cannot check
whether it breaks the syntax for Japanese dates - could somebody,
please, check it?

Best regards, Michael.
