added variant of the ^U command with string building: the EU command

it became apparent, that something like this is very useful,
when constructing the contents of a q-register without
editing it.
I have decided against introducing another modifier for toggling
string building. Most commands have string building enabled and it
doesn't hurt. For the few exceptions, an alternative variant can
be introduced.
