[bug-recutils] join basics. Want to extract records, driven from a list of "last names".

[recutils]

Have a list of 30 'last_name' values in a file
foo.rec;
and a 16000 record list of people in people.rec, which also has 'last_name' 
values
and many other fields.

Want to extract (recsel?) just those people.rec records
w/the 30 last names in foo.rec.  
How do I do this?

This is obviously wrong:

    recsel -t foo.rec -j last_name  people.rec

$ head -3 foo.rec
last_name: Hardy

last_name: Walters
