Nice idea, I had some annoyance about it too once.
What I would comment that as I know you may not relay that you use
ASCII [c += 32] but should use tolower(3). [read manpage, do think of e.g.
umlauts].
And as I know in VFAT the first letter is shown as uppercase [in flying
windozer..]. [but you may type them as you wish..]
