AFAICS, those functions can be built on top of the existing filesystem
functionality. Thus they are lower priority for me than
internationalization.
But, yes, they would be useful, and I have often had to hand-coded both
recursion and bulk load/save. That's the point of the convenience header;
to be able to have at hand convenient functionality built on top of the
library's core functionality.
