Just did something like that: committed the coding style cleanup, then
unit-tests, then minor code cleanups. The huge patch adding support for
nested groups is here:

I took some inspiration from printableToString and added
unescapeString() to KConfigUtils. It may be useful to move this function
to KStringHandler later, but for now I wanted all changes to be self
contained.

Like for unescapeString(), I can refactor this afterwards.
