Hi.

(Note: this is with graphite/carbon/whisper trunk.)

I was trying to add a new section to storage-schemas.conf with a retention setting of "10s:6h,1m:1w,10m:5y".  It initially chokes on the "m", but if I comment out all but the first component, it complains about the "6h":

I managed to work around it by using "10:2160,60:10080,600:262974" instead, but I'd prefer to use the human-readable form.

thanks.
