[INDOLOGY] difference between "vinculum" and "macrion" (Re: Unicode font for ancient and modern Tamil

[Jean-Luc Chevillard]

Dear Manu, dear Satyanad, dear Charles and dear list members,

if I understand correctly,
the nature of a vinculum is that it "ties together", by means of an 
overline, several items,
like in the example provided by Satyanad,
namely \overline{x+y}

However, sometimes, there is ONLY ONE element which is kept prisoner by 
the vinculum, as in the examples provided as screenshots taken from one 
of my books

+ the definition of a "rising factorial power"
	(on page x of Graham-Knuth-Patashnik[1994]
+ the binomial theorem for factorial powers
	(on page 245 of the same)

I include also a scan of the cover of that book, for easy identification
(ISBN 0-201-55802-5)

That would mean that a "vinculum" over a single letter
is longer that a "macron" over a single letter.
