Re-correct commit 1.73, but this time in a way that does not cause

all column-headers to print in lowercase by default.  I was in too
much of a rush in committing 1.75, and didn't notice that the case
had changed.  This time I did considerably more testing, and used
'diff' instead of just quickly eyeballing the results...

Apologies.  I expect this means the dunce cap is mine for awhile.
If this doesn't work, I'll just drop back to 1.72 and hide under
my desk for awhile.
