I happened to write a software "Gistore" to backup arbitrary files and directories using Git, and it will save interesting things in .git/info/exclude. For your case, you could write .gitignore as:

    /modules/*
    !/modules/interesting
    !/modules/interesting/**

You can find my code in Gistore to generate proper .gitignore here:

    https://github.com/jiangxin/gistore/blob/master/lib/gistore/repo.rb#L228

Because I will ignore all files except what I want, the ignore file would be:

   *
    !/modules
    !/modules/interesting
    !/modules/interesting/**
