I remember IBM punch card was 80 char wide.  And last 8 column was
supposed to be used for optional line number. 

Thus 80-8=72. I think that is the reasion behind 72 char per line
custom.  This explain why not 65 nor 75.

Of course, indenting message on VT-100 like consoles like others has
mentioned is the reason why this rule survived untill now.


PS: I used to type that card. Teletype and (paper punch) tape was great
improvement over that card :-)
