Function ExpandRecursiveRoot

src/Preferences.cpp:1893–1905

Walk `root` recursively, appending `root` itself and every descendant directory to `out`. Uses CDirIterator::Dir so hidden subdirs are included (matches the runtime watcher's behaviour -- the watcher's AddTree() visits hidden too).

// subdirs are included (matches the runtime watcher's behaviour --
// the watcher's AddTree() visits hidden too).
void ExpandRecursiveRoot(const CPath & root, CPreferences::PathList & out)
{
	if (!root.IsOk() || !root.DirExists()) {
		return;
	}
	out.push_back(root);
	CDirIterator dir(root);
	for (CPath sub = dir.GetFirstFile(CDirIterator::Dir);
		sub.IsOk();
		sub = dir.GetNextFile()) {
		ExpandRecursiveRoot(root.JoinPaths(sub), out);
	}
}
