It seems like the shell is eating an extra newline. Try typing an empty
line after assemble_fam2:
$ set -x
$ assemble_fam1
+ fred
++ echo fred
+ FSTONES=fred
+ FSTONES=wilma:bam-bam:fred
$ assemble_fam2
+ barney
++ echo barney
+ RUBBLES=barney
$
+ RUBBLES=betty:pebbles:barney
$ say_families
+ say_families
+ echo Flintstones=wilma:bam-bam:fred
Flintstones=wilma:bam-bam:fred
+ echo Rubbles=betty:pebbles:barney
Rubbles=betty:pebbles:barney
