I think I've found the issue. The input contains:

SRC_URI="${SRC_PATH}/X${MY_SV}src-1.tgz
    ${SRC_PATH}/X${MY_SV}src-2.tgz

    ${SRC_PATH}/X${MY_SV}src-5.tgz
    doc? ( ${SRC_PATH}/X${MY_SV}src-6.tgz
        ${SRC_PATH}/X${MY_SV}src-7.tgz )"

The code doesn't handle stuff like this. I had another idea, though. I could process each variable as I read it from the file. In bash, a variable has to be defined first to be interpolated into one occuring later. I can interpolate each variable as I read it in, so there is no need for a deptree and recursive functions.
