History of ellipsis in charmap and locale specifications?

[Carlos O'Donell]

Mike, Rafal,

Historically charmaps and locales support different kinds of ellipsis 
expansion including: 
"....(2)....", 
"....", 
"...", 
"..(2)..", 
and "..". 

POSIX seems to define only "..." for charmaps and locales.

Do we know where the rest of these came from?

I could reverse engineer what the code does for them, but in some cases
it's kind of odd what they do and in some cases they are aliases for
eachother.
