Widows and orphans are variables which you can define in HTML/CSS. If you use DRMed ebooks, like the ones you would buy at Kobo, it might be a bit difficult to influence. Perhaps it would even be necessary to remove the DRM. I'm not sure, because I've never owned a DRMed ebook.

If you're using "free" ePubs and Calibre it's pretty easy to change. Normally, I wouldn't recommend it though, because of, literally, centuries old conventions governing the layout of PRINTED material!

So, if you're using an ereader configured to display roughly the same amount of text you might find on a paperback page, don't touch! It'll look pretty much like what the publisher intended. I'm using these "normal" settings and never got pis*ed enough to start editing.

But, you've really raised an interesting question here! Being allowed to increase the font size is afterall a much vaunted feature of ereaders. Now that I think about it, quite a large proportion of posts on the forum are concerning greater font flexibility!

I haven't found a font-size-speciffic "w. and o." tag or function in HTML/CSS yet, but I'm guessing it might be real hard to implement cross-platform.

Since the reading applications on ereaders are nothing but glorified(or stunted) HTML viewers, one likely easy way to make it work would be proprietary. At a certain, device-speciffic, font size(the one where it begins to look ridiculous) the reader app just ignores widows and orphans.

Ah, well I'm gonna concur, my eyes aren't getting any better.
