Hi Ævar,

Thanks in advance for the suggestions and catching my memory leak.

Perhaps we could also continue down that path and do this with just one
allocation for that "oid/resolution_exists" side-data. I.e. you'd have a
second string_list in the struct, have a non-NULL util mean "resolution
exists", and the "string" there would be nodup'd (we could refer to the
"string" in the first one).

Since I am removing the "resolution exists" field, I modified your changes
to use the util to only hold the abbrev.
