Camel-cased strings with one-letter parts lead to unexpected results

[Golmote]

This is correct :
Case.camel('This is a test') === "thisIsATest"

But the contrary seems unexpected :
Case.upper('thisIsATest') === "THIS IS ATEST"
Case.lower('thisIsATest') === "this is atest"
and the same goes for other manipulations

Hmm. I thought i'd fixed that. Clearly i didn't write a test for it. It's a side effect of trying to support acronyms like my employer's name (ESHA). When busting them out of camel/squish, it's supposed to keep serial caps together and break at the last one before the caps end. Instead it is keeping them with the following word. I have no time to work on it now. Maybe Thursday... Of course, you are welcome to beat me to it. :)
