The changes to HELLO do more that the above says. I don't think I
understand the reason for the change in the "South Asia" line.
The South Asia line was correcting the Odia greeting, which I had changed previously (from "Listen" to "Namaskaar")
This is unrelated, and I see no reason to rename the variable in a
backward-incompatible way. It's just a variable, so it doesn't have
to be named rigorously correct. If we were discussing new code, the
correction would have had its place, but not now, 16 years after it
was introduced.
This variable name is somewhat misleading. When I searched "iso 638", online to see whether the language codes were updated or not,
it showed me results for oven boards, later when searching "iso 638 languages" I realized that the correct standard number is 639.
There was also a FIXME above it, so I fixed that.
If there is a backward-compatible way to change it please tell me, or if you still feel the change is not warranted, I will revert this it.
I don't think we should rename variables and functions. It's just a
lot of hassle for us (defalias etc.) and potentially for others, and
the gain is very small. This variable doesn't even say "oriya", just
"ori". Let's not be too radical here.
Then I should only rename in etc/HELLO, and in (set-language-info-alist) of lisp/language/indian.el.
We cannot rename an input method we had for almost 20 years. If there
is some way of having an alias for an input method (I don't think so,
but maybe I'm missing something), let's use that; otherwise we will
have either to leave the old name alone or define a new input method
that is an exact copy of the old one, except for the name and the
mode-line indicator.
How about I make a new Odia input system, just like the ones which I had made for the other scripts, and leave the old ones alone?
