INDEX-8 not updated by portsnap?

[Barbara]

It seems that starting with the comms/umcs7840 commit, INDEX-8 isn't updated 
running portsnap.

for example:
$ ll /usr/ports/sysutils/webmin/Makefile 
-rw-r--r--  1 root  wheel  3687 Dec 10 18:18 
/usr/ports/sysutils/webmin/Makefile

$ grep ^PORTVERSION /usr/ports/sysutils/webmin/Makefile 
PORTVERSION=	1.530

$ grep ^webmin INDEX-8 | cut -d "|" -f 1
webmin-1.520

I had to get a fresh INDEX-8 running make fetchindex.
