This bit is a problem for me, as my configuration includes the following:
| domainlist local_domains = \
|         @[] : \
|         +internal_domains : \
|         +sauce_domains : \
|         +non_sauce_domains : \
|         AUTODNS_DOMAIN : \
|         lsearch;LOCALBATCH : \
|         dsearch;ALIASDIR


So I started looking at adding a "member" expansion to expand.c, which can
look something up as a domain in a domainlist or an address in an address
list.

Unfortunately, I'm finding match.c a little hard to follow, and I'm not
sure which function I should be calling. I'm assuming that it would be
match_isinlist(), and that I'd also need to specify whether it's a hostlist
an addresslist or a domainlist in my expansion.

Would other people consider this type of expansion to be useful (as AFAICT,
it's only useful in this kind of situation)?
