[TUHS] tabs vs spaces - entab, detab

[Brantley Coile]

I'm pretty sure people knew the value of PI before 1611, when the
Authorized Version was published, and that people had a pretty good 
idea when the event described in 1 Kings 7 happened, a bit 
before 900 BC.  They used 3.1605 for the ratio in that time, I believe.

The values in the Bible are as one would explain to someone in conversation
about something else.  If I said something was 10 feet across and 30 feet around  
in normal conversation, an error of a foot and a half would be close 
enough.  When buying material, I use 4 as PI and trim to fit.
