Oops.  (I went too many places looking for examples and still did not get that somehow.
I had a ton of sleep last night so should not make more mistakes today hopefully.)

Yes, I see that.

This is know.

Thanks for refreshing me on this. (The case of Serbo-Croatian 'sh' now comes back.)

I thought I was supposed to do all the first group of retired changes (I've already done 'lut', 'lushootseed', 
but have put in inside of  brackets for now; let me know when you want it).

(O.k. thought I was doing minor clerical work here, following your directives.
And anyway, I am finally getting shy, now that I got to do all this, but o.k.)

That was sort of what I suspected; sorry.

(It would have been almost easier for you to just copy and paste these than to train me would not it have?)
