The sorting characteristics of C are strict ASCII order, spaces
significant.

The characteristics of en_* are dictionary order, more spaces sort after
fewer spaces:

$ LANG=en_GB sort /tmp/ol
fredbrooks
fred brooks
Fredbrooks
Fred Brooks
Fred Brooks
FredBuck
Fred Buck
Fred Buck

$ LANG=C sort /tmp/ol
Fred Brooks
Fred Buck
Fred Brooks
Fred Buck
FredBuck
Fredbrooks
fred brooks
fredbrooks

So I suspect that if you want a mixture of these characteristics, you
will have to write your own locale. Don't ask me how...
