kilo K is now uppercase; loop k is lowercase
kilo K is now uppercase; loop k is lowercase

Now there is no conflict.

After adding i j & k (to return the current do-loop indices for the
current, enclosing, and third do-loop), I saw that the loop k was
aliasing the conversion (* 1000) k - which, according to IEC guidelines,
should be lowercase. Oh well. Now it isn't any more.

This could still confuse case-insensitive dict searches, but since we
currently don't do that...
