the localrc is really just executable shell, which means there are
tons of edgecases where you can't treat it the same as simple
assignment a=b.
Instead of trying to be smart about things and reduce duplication in
the localrc files, just do the naive thing and stack up all the shell
declarations in order. When evaluated in shell they will end up
stacking up as expected.

It's important when setting localrc name=value that there are no
spaces around the = sign, otherwise it doesn't work. Remember to treat
localrc special from the iniset portions.
