oh so this suggests a different answer to my "overlapping matches"
question (in the message on the F&O document that I cross posted here
and to the query-commets list) than the one Jeni said I ought to
expect....
if the regexp is aa and the string is aaa, then your description would
suggest that aa gets matched against the substrings of aaa:
a
aa
aaa
a
aa
a
and matches the 2nd and 5th of these, so returning (1,2).
